i'd have died if he got cookies

LMAO
I am starting to understand this filter function maybe lol
that's a good one to learn
.filter(e,i,array)
the 2 important things for those types of methods:
- what does it return
- does it mutate the original
yeah that is what I am trying to figure out my mind is going crazy with it lol
lol
this stupid challenge, will we ever see a challenge like that in the real world of web design or even back end
which?
wherefor art thou
It is like so confusing to understand
i use arrays of objects often
learning to search through them is useful
yeah but it is like I am trying to search throuh them the wrong way with filter
then don't use filter lol
it is like I am not figuring out what I have to ask, just when I thought I had it boom it bends me over and lifts up my kilt and you know LOL
the same thing is true with for loops
it looks like i used
filter() when i did it
it says to use for loops and filter or for loops
you know what I mean and this is the closest I got to it
I can't see the challenge, but I believe the for loop is used to iterate through the array
i used
filter() and inside the filter callback i used Object.keys() and every()
yeah I tried to use every too lol and object.keys() too
and with each item in the array you filter it out
function whatIsInAName(collection, source) {
// What's in a name?
var arr = [];
// Only change code below this line
var sourceKeys = Object.keys(source);
var sourceVals = Object.values(source);
for (var i = 0; i < collection.length; i++) {
for (var j = 0; j < sourceKeys.length; j++) {
if (collection[i].hasOwnProperty(sourceKeys[j])) {
if (collection[i][sourceKeys[j]] === sourceVals[j]) {
arr.push(collection[i]);
console.log(collection[i][sourceKeys[j]]);
}
}
}
}
console.dir(arr);
// Only change code above this line
return 'arr';
}
oh wait yeah its a little more complicated than that
the problem with this it worked fine with the first 2 and then when they have the dam c:2 it just was like nooooo lol
return 'arr'; ?
that is for the fcc challenge
thats returning a string 'arr'
not the variable arr
well 'arr' was because I was fixing something
ok
and forgot to change it back lol
but it was I had to reload my browser 2 times and that is what fixed it lol
i think one problem is you're pushing duplicates into your array
I was then trying to use the filter and every methods or functions and just got confused
and also you're not verifying all properties are in each object
whatIsInAName([{ "a": 1, "b": 2 }, { "a": 1 }, { "a": 1, "b": 2, "c": 2 }], { "a": 1, "b": 2 }); for this one when you first check the a property ` in this one the 2nd element will get pushed into arr, because both have a property with a and the value to 1
but it doesn't have a property b, so it shouldn't be added
this is my issue with that code lol
yes that is what I am trying to check right now @coymeetsworld I am trying to figure out how to say in code
check the second property as well and that is why I decided to try the filter() method and every() but because I simply am not understanding them well enough or how to check it I am stuck I just want to cuss at javascript lol
so I was trying to use every() so it could say check all properties but I am slightly stuck on that too in how to go about that
hello, I have this code is there a way i can nest filter and map methods
` ``
var filter = watchList.filter((value) => {
return value.imdbRating.valueOf() >= 8.0;
})
var filteredList = filter.map((value) => {
return {Title:value["Title"], imdbRating:value["imdbRating"]};
});
```
@daddycardona the filter method is used to remove elements in the array that match a certain criteria
bleh i can't get it less than 7 lines without making it stupid ugly
so that would be a good use of it here. Instead of pushing into a new array, it would be better to just use the array you have and filter that out
for instance, if source object has a property of a, filter all objects out of collection that don't have that property
then you're left with only objects that have a property of a, next thing you do is compare the value of property a in the source object to the property a values of the objects inside collection
oh okay I get that but that is what I was trying to do with it but I was confused
Object.keys, hasOwnProperty, and filter were the 3 key functions I used
@ankorGH You probably want to chain them rather than nest them.
watchList.filter().map()
hmm I tried all that and now I am back to the begining again with this challenge @coymeetsworld
@daddycardona maybe start over, and try to work through the challenge incrementally
first thing you need to do is have a way to go through each object in the collection array.
that is what I am doing now with the filter method, to trully understand it but it is like I don't understand it all now and I am like wt#
@daddycardona
keys.every() will return true if every key passes the condition as true
item.hasOwnProperty(key) && item[key] === source[key]; so this is the condition that you want to test for each keykeys.every() will return true if every key passes the condition as true
@daddycardona
var valid = true
for each key
if no key or value doesnt match - valid = false
endfor
if (valid) push
omg i'm so dumb, i forgot arrow functions had implicit return
so it can be done in single line without looking horrible
yeah its nice
when I refactored my d3 projects they looked alot cleaner
my d3 is just a ton of chained methods
looks like jquery gone wrong
Okay I see @sjames1958gm but i am like about to try what you are saying
@sjames1958gm thanks it worked :smile:
ankorgh sends brownie points to @sjames1958gm :sparkles: :thumbsup: :sparkles:
api offline
lol @thekholm80
yeah you still have to chain
but like the callbacks can look alot more simplified
i bet, especially for like the scale and all that
man, i haven't thought about d3 in a while
let minQtr = d3.min(gdpData.data, function(d) { return d[0]; }); goes to let minQtr = d3.min(gdpData.data, d => d[0]);
var bar = chart.selectAll("g")
.data(gdpData.data)
.enter().append("rect")
.attr("title", "GDP")
- .attr("x", function(d) { return x(d[0]); })
- .attr("y", function(d) { return y(d[1]); })
- .attr("height", function(d) { return chartHeight - y(d[1]); })
+ .attr("x", (d) => x(d[0]))
+ .attr("y", (d) => y(d[1]))
+ .attr("height", (d) => CHART_HEIGHT - y(d[1]))
.attr("width", barWidth - 1)
.on("mouseout", function() {
hideTooltip();
i see
i was just looking at
node.style('left', (d) => { return d.x + 'px'; })
.style('top', (d) => { return d.y + 'px'; })
.call(force.drag);
link.attr('x1', (d) => { return d.source.x })
.attr('y1', (d) => { return d.source.y })
.attr('x2', (d) => { return d.target.x })
.attr('y2', (d) => { return d.target.y });would look a lot cleaner with implicit return
yeah a little
so I was trying to understand what you are saying agian @sjames1958gm and now I just am more confused well time to watch something relax my mind it has been a crazy weekend thanks to @thekholm80 @coymeetsworld @sjames1958gm

stupid api
@daddycardona don't give up, you'll get it
this challenge for me was my first taste of callback hell
that sideways pyramid is a pain in the butt
I hope so it is like I get it one minute and then bam i forgot everything we were talking about the next lol
just try and focus on one thing at a time, revisit those functions and make sure you understand how they work. That should help too
I have one more question, when I do the filter() method I should use the every() method on the inside of it? also should I filter the collection array of objects or source object? I am guessing collection? @coymeetsworld @sjames1958gm @thekholm80
I am getting a strange quirk.postion: absolute hides the element even after i added z-index: 99.
the above mentioned statement is on line-138 in the given codepen below.
https://codepen.io/neel111/pen/EvMmgZ
by removing the position: absolute the element show up. Why position: absolute is hidding the element?
@daddycardona i filtered the collection, then in the callback used every on the keys and returned where key & value matched the search value
Okay so I have this but it is not done make sure I get this
var something = collection.filter(function(e, i) {
Object.keys(source).every(function(key, item) {
close
not sure what the
item is
just like element, item, array in filter but key, item, array?
in this wouldn't
item be the index of the current element?
i have to look up
every()
yeah
every(element, index, array)
and filter as well
oh yeah I was reading it as well dammit lol
Callback parameter Definition
value The value of the array element.
index The numeric index of the array element.
array1 The array object that contains the element.
so
function whatIsInAName (collection, source) {
var arr = [];
// ...
return arr;
}
filter will return an array so we can assign the output of filter to arr
function whatIsInAName (collection, source) {
var arr = [];
arr = collection.filter(function(item) {
// ...
});
return arr;
}
so I don't need var something lol
Oh I don't need the second parameter here either okay
the criteria for the filter should look at each key of the
item
and compare it to what is in
source
if all the keys and values match
the element should be returned
You should do a video to something close to something like these challenges but not the actual challenges lol
haha
i'm way too lazy
remember that to get the objects out of the
filter() you have to return them, sofunction whatIsInAName (collection, source) {
var arr = [];
arr = collection.filter(function(item) {
return // ...
});
return arr;
}
so now is when you would look into every ()
right
for every() to work, you need an array
which is where
Object.keys(source) comes in
so you have to break down soure
Object.keys(source) will create an array of the keys in source
then
every() will let you look at each element in that array and check it against item
yeah okay so your return for filter should be Object.keys(source).every(fn//)
remember to get any values out of
every() you need to return them
yes
yeah okay so your return for filter should be Object.keys(source).every(fn//)
so now you're at
function whatIsInAName (collection, source) {
var arr = [];
arr = collection.filter(function(item) {
return Object.keys(source).every(fn//)
});
return arr;
}
just put in the comparison in
every() and you should be there
okay that makes sense, however every returns true or false
Oh okay so it will return true if every key and value is okay therefor the filter return will return that array object to arr
there you go
filter requires true or false, so that's what we're feeding it
Oh shoot I am stupid lol
nah, you're almost there
this is not the simplest problem, and not the simplest solution
dammit that is why if you put return a string it just saying that it is true and returns it
yep
strings are 'truthy'
so your
every() should just check the 2 values and return whether they're a match or not
and bam, you're done
I was so confused, and i read the dam mdn and msn and looked at a hundred videos because I did not understand it is a true or false boolean type crap it needs to say true or false no maybes or possibly lol
rofl
since JS isn't a typed language, a lot of weird stuff can happen
I see now maybe I cand understand this now I hope because I have to get the rest of the solution inside .every(function
I am hoping I understand what you all are saying now lol I am a lost sheep looking for it's flock
the last thing to remember is that
Object.keys() is going to create an array of keys from source so every() is going to look at each key. To compare the values you need to use the [] notation on the objects since you're going to be using a variable
so if
var source = {a: 1, b: 2};
var arr = Object.keys(source);
console.log(arr) // => [a, b]
then
arr.every(function(key) {
console.log(source[key]) // => 1 2
});
oh okay thank you
compare that to the current item in collection and you're there
thanks @Manish-Giri

@daddycardona did you get it?
help me understand too
array functions
yes once I understood what I was doing wrong lol
function array() { ... }
pretty simple
@thekholm80
@daddycardona congrats!
I actually had done something before but it did not work because I am an idiot lmao
i hope i didn't just feed you the answer
it is like a weight lifted off my shoulder, next time I will just ask stackoverflow lmao
the important thing is that you understand why it works
No I did a check before but I never did understand that filter was an true or false and so I never was able to make filter work lmao
I did it with a for loop before lol
basically filter is asking "should i return the current value?"
that's why the callback should be true/false
I need to re read it I bet it says exactly what you did lol
@thekholm80 this is what happens when I skim and to tired to read properly
callback
Function is a predicate, to test each element of the array. Return true to keep the element, false otherwise, taking three arguments: exactly what I have been missing this whole time was right in my face lol
lol yeah that happens
they could make it a little easier to understand though
I read this before but my brain did not work lol
I feel as though I should pay for treehouse because I think it is more indepth on subjects for me. Like I flew by all the other challenges but i got to the api bs and all inbetween this one and api and was confused. I didn't learn enough to do the projects but if they had videos and I could follow along it would have been easier. Some of these force feed you the answers lol
I'm not familiar with treehouse, but if you're serious about learning this stuff i'd totally agree that it's good to look at sources outside freecodecamp, especially if freecodecamp isn't presenting the information in a way that works well for you
after i finished front end i started taking courses all over the place. I think you have to if you want to continue
yes this is definitely a good starting point but I am slow lmao so I need to get more understanding and I hate when I look something up and it's someone comepleting the challenge its like wt#
codeacademy seems pretty similar to here as well

Shall i learn bootstrap4 or semantic ui?
Shall i learn bootstrap4 or semantic ui?
whichever you prefer @NeelDVirus, FCC covers bootstrap so unless you really like semantic i would stick with that.
but dont invest a lot of time in either of them, as eventually you should move away from those frameworks and implement the CSS/JS on your own
@coymeetsworld yeah i learned bootstrap3 and boostrap3 doesn't seems so fascinating to me. Bootstrap 4 is fascinating but it is still in beta version(risky to use), and on the other side semantic ui is much fascinating but more harder to get used to it.
Now this is where i am confused :D :D
Now this is where i am confused :D :D
yeah i am not gonna be reliant on either one
I don't know anything about Semantic UI, but seems to be similar
if you really want to use it because of some features it has over BS then go for it

Given two strings, find the number of common characters between them.
Example
For s1 = "aabcc" and s2 = "adcaa", the output should be
commonCharacterCount(s1, s2) = 3.
Strings have 3 common characters - 2 "a"s and 1 "c".
function commonCharacterCount(s1, s2) {
s1 = s1.split("");
s2 = s2.split("");
var s1Length = s1.length;
var s2Length = s2.length;
var count = 0;
for(let i = 0; i < s1Length; i++){
for(let j = 0; j < s2Length; j++){
if(s1[i] === s2[j] && s1[i] != null){
console.log(s1[i]+" is equal to "+s2[j]);

@KJKSLOVE Welcome to Free code Camp Community
hey @sjames1958gm yeah it will In this case I only need to splice the second one ssince I will run the first 1 from start till the end
@tiagocorreiaalmeida Also, if you get a match you should break; from inner loop or you will get multiple matches
yeah was thinking about return but it would stop the entire function so yeah loop is the trick, thanks

hi everyone, I have a stupid question regarding linking stylesheet to html
I link the css file in the head of the html file which is in the same directory with this
```<link rel="stylesheet" type="text/css" href="styles.css">
Yes.
Yes.
Go on.
and style the body in the css file however nothing happens
@Pethaf here is the code, it is very short
Have you tried adding a custom class in your css and on your webpage? Just to check that your css is loaded properly?
It could be bootstrap interfering.
I.e. add something like
.test { color: maroon; min-width: 80vw;} to your styles.css and a <div class="test"></div> to your html.
For a = [-1, 150, 190, 170, -1, -1, 160, 180], the output should be
sortByHeight(a) = [-1, 150, 160, 170, -1, -1, 180, 190]. how can I avoid chaging those array positions?
sortByHeight(a) = [-1, 150, 160, 170, -1, -1, 180, 190]. how can I avoid chaging those array positions?

I got the one after wherfore are thou
:tada:
search and replace was very easy I couldn't sleep so it took me like 20 minutes and boom LOL
good job!
Now I have an issue with a switch case in pig latin
switch (str.charAt(0)) {
case 'a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U':
str += 'way';
break;
should that work?
switch (str.charAt(0)) {
case 'a':
case 'e':
....
Or should I be using something else like charcode numbers for this instead
Oh I have to use it like that then break after "u"
okay I don't know what I a m thinking lol
I swore you could do it like the way I was doing lol
i've never seen it that way
that doesn't necessarily mean it won't work, just that i've never seen it
hey guys :D @daddycardona @thekholm80 :wave:
hey buddy
how's the great frozen north?
getting cooler finally
hey buuuuudddy In my Polly Shore voice
summer's mostly over
but weirdly it's been humid
Oh you more north than I am, you use to hang out with the weekend lol
it was 95 here yesterday but we're supposed to be in the high 80s this weekend
I guess that's an improvement
Dude its 80 here
i hate anything over 70 lol
i hate anything over 25
certainly hate anything near the boiling point of water

Hey there! Is anyone else unable to sign into the beta? I'm getting an error message, but I can view the beta map while not signed in
pfft you think you're so cool with your metric system
@jenkuy they disabled beta sign-in if you don't already have a login
anyway, i've got to go yell at some people, back later
@DarrenfJ I already have an account, I just haven't logged into it in 2 weeks
@jenkuy ah.. then login info is here: https://forum.freecodecamp.org/t/frequently-asked-questions-about-the-freecodecamp-beta/134331/28
that worked for me when i was locked out
translatePigLatin("glove") should return "oveglay". why lol
it don't say that in the description
@DarrenfJ Yeah, that is what I am using and am getting the error from: "Oops! Something went wrong. Please try again later"
If it is just me, then I'll try again tomorrow or so :)
stupid pig latin which is basically english

@jenkuy somebody last night said the beta was down when/around when the main site went down.. possibly related? And they haven;t gotten to fixing it yet?
the api is offline here and they haven't gotten to fixing that either...

So @DarrenfJ why the hell did they ad glove to
oveglay it did not say that in the description lol
don't they have some rule about taking two constenants if the vowel is after them?
I know I am confused with this I had the whole dam thing working lol
I just added a switch case for g
if( charAt(1) == 'l') that fixed it
Okay I realized I read it wrong, I did not know what a consanant cluster is lol
But I researched it oh well I will redo it later :)
Help please?
I am trying to make a submit button that submits an email to "https://www.freecodecamp.com/email-submit" i added this into an action like so action="action="https://www.freecodecamp.com/email-submit"" but it will not work with the submit button ive made
@daddycardona i thin i did some run pullin out the start of the array... running through the array (split str into an array) and found the first vowel (having saved the constenants or something)
probably over thinking it myself though now
lemme go check
yah.. had a vowel check and basically peeled off the first letter until i hit a vowel than adddedit to 'ay' on the back.. had the special case of if starting with a vowel add 'way' at the back
anybody?
brb gonna check it some more
@ajhernandez95 is that challenge or something?
@texas2010 yeah its a project for a product landing page
oh
yeah so any help?
@ajhernandez95 why do you have action twice?
action="action="https://www.freecodecamp.com/email-submit""
i just copied and pasted that was my bad but its not like that in the code
its action="https://www.freecodecamp.com/email-submit"
can someone say why is this while loop infinite? this is the cash in drawer problem
while (change>0 && cid[0][1]>0) {
switch (true) {
case (change >= 100):
if (cid[8][1]>0) {
change -=100;
changearr[0][1] += 100;
cid[8][1] -= 100;
break;
}
case (change >= 20):
if (cid[7][1]>0) {
change -=20;
changearr[1][1] += 20;
cid[7][1] -= 20;
break;
}
case (change >= 10):
if (cid[6][1]>0) {
change -=10;
changearr[2][1] += 10;
cid[6][1] -= 10;
break;
}
case (change >= 5):
if (cid[5][1]>0) {
change -=5;
changearr[3][1] += 5;
cid[5][1] -= 5;
break;
}
case (change >= 1):
if (cid[4][1]>0) {
change -=1;
changearr[4][1] += 1;
cid[4][1] -= 1;
break;
}
case (change >= 0.25):
if (cid[3][1]>0) {
change -=0.25;
changearr[5][1] += 0.25;
cid[3][1] -= 0.25;
break;
}
case (change >= 0.1):
if (cid[2][1]>0) {
change -=0.1;
changearr[6][1] += 0.1;
cid[2][1] -= 0.1;
break;
}
case (change >= 0.05):
if (cid[1][1]>0) {
change -=0.05;
changearr[7][1] += 0.05;
cid[1][1] -= 0.05;
break;
}
case (change >= 0.01):
if (cid[0][1]>0) {
change -=0.01;
changearr[8][1] += 0.01;
cid[0][1] -= 0.01;
break;
}
default:
break;
}
}
this switch is decreasing change due, increasing change array, and decreasing cash in drawer
@gogminsam It could be precision problem if the result ends up < 0.01 it will never end, if you hit the default: then console.log the value and set change to 0
@sjames1958gm i did that already, infinite loop is fixed now, but now i get one less penny at the end, is this the precision problem? how can ii overcome this problem?
@gogminsam I converted everything to pennies (multiplied everything by 100) then converted back at the end.
@sjames1958gm thanks, ill try that one

i think manish has finished most of the projects anyway.. only way to keep his streak is through the lerve of the helping people out
surely there's an unfinished D3 or something he could turn in
lol
a quick microservice
hehe
yeah I have one last d3 left and the dungeon
then i'll finish data viz
some of those microservice projects take like an hour
then I can retire and settle in nepal
lookit that streak!
566 days
starting tomorrow: day 1
aw come on yours would be 586 days
they should reset his cookies too
but like i said then we'll be freeeeeee!!!!
@DarrenfJ
that's if you don't log in
logged in it's something ridiculous like almost 800 days
but i'm good i got one in for today
but since ye ole days of yore when the helpRoom was actually active I've not felt like I've really earned it anymore :/
I don't miss seeing the same question 30x a day, but it was nice having some activity here
@DarrenfJ look at that
logged in or not, you'll be the reigning champion
:bow:
i read about a guy who had 1000 days in GitHub back when they tracked streaks and he wrote a nice post about choosing to give it up so he could focus on quality and not doing something every day.. so he could pick and choose when to work on stuff
the streaks at least kept me working one something everyday.. but giving it up might be a good thang :D
lol
@DarrenfJ we always have our side gig to fall back on
:smiling_imp:
i know!
This message was deleted

gotta get cracking on that myself
@thekholm80 oui!

on the node install or the node-sass package?

Hi all - can anyone help me get my react recipe app deployed on Heroku? I've linked the github repository, but confused on where to go from here.
@abohannon do you have the heroku cli installed?
@thekholm80 yea. And I started going through the tutorial, but it seems its starting from scratch. I just want to deploy my already existing app.
@thekholm80 lol wow
@abohannon actually, this is the guide i followed
the syntax is similar to git
@thekholm80 rad i'll check it out thanks
abohannon sends brownie points to @thekholm80 :sparkles: :thumbsup: :sparkles:
api offline
i lied that isn't the guide i used
I can't find the one i did use
@Manish-Giri if i were rich i'd pay $250k to punch that guy in the face
@thekholm80 lol
:joy_cat:
so my package.json file has this
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test --env=jsdom",
"eject": "react-scripts eject"
},
and the heroku tutorial is asking for this:
"scripts": {
"start": "node server.js"
}
you should make a Procfile
wait, are you deploying without bundling?
also, do you have a server or is this front end only?
@thekholm80 I got tired of using codepen for react projects because my files were crazy long. Figured deploying on Heroku would allow me to showcase my work utilizing the standard one component one file practice. But maybe I'm wrong.
This is the github repo https://github.com/abohannon/react-recipe-box
@abohannon i see
that is linked
heroku, as far as i know, requires a back end
i use firebase for my react only projects
cool, i'll check it out. thank you
i'll see if i can find an easy write-up for deployment there
@abohannon this looks good https://gautamthapar.me/deploying-react-app-firebase/

@thekholm80
The quick brown fox jumps over the lazy dog.

yep

it's a tricky letter
you got the other 25 though, right?
still a good score
lol
trying to do this
looks rough
where's that guy that's ranked 2kyu? he could tell you how to do it without even looking at the problem
:joy:
did you know he's no longer ranked 2 kyu
he's moved on to 1 kyu
1?
:fire:
geniouuus
lol
oh wow I finished the kata and lemme show you the top solution
i bet his first whiteboard interview will be fun
public class PangramChecker {
public static boolean check(String sentence) {
String MaleLitery = "qwertyuiopasdfghjklzxcvbnm", DuzeLitery = "QWERTYUIOPASDFGHJKLZXCVBNM";
char[] TablicaCharow = new char[sentence.length()];
char[] MaleLitery1 = new char[MaleLitery.length()];
char[] DuzeLitery1 = new char[DuzeLitery.length()];
int[] TablicaIlosciLiter = new int[MaleLitery.length()];
boolean[] TablicaPrawdy = new boolean[MaleLitery.length()];
boolean result = true;
for (int i = 0; i < sentence.length(); i++) {
TablicaCharow[i] = sentence.charAt(i);
}
for (int i = 0; i < MaleLitery.length(); i++) {
MaleLitery1[i] = MaleLitery.charAt(i);
DuzeLitery1[i] = DuzeLitery.charAt(i);
TablicaIlosciLiter[i] = 0;
}
for (int i = 0; i < sentence.length(); i++) {
for (int j = 0; j < MaleLitery.length(); j++) {
if (TablicaCharow[i] == MaleLitery1[j]||TablicaCharow[i] == DuzeLitery1[j]) {
TablicaIlosciLiter[j]++;
}
}
}
for (int i = 0; i < TablicaIlosciLiter.length; i++) {
if (TablicaIlosciLiter[i] >0)
{
TablicaPrawdy[i]=true;
}
else
{
TablicaPrawdy[i]=false;
}
result=result&&TablicaPrawdy[i];
}
return result;
}
}
this is the current top solution
this is mine
import java.util.*;
public class PangramChecker {
public boolean check(String sentence){
//code
String replaced = sentence.replaceAll("[^A-Za-z]", "");
Set<String> letters = new HashSet<>(Arrays.asList(replaced.split("")));
return letters.size() >= 26;
}
}
rofl
pfft anyone can just import the answer
:joy_cat:
import java.kata.answer;
but yeah you're right his whiteboard interview would be fun
lol
luckily he's still like 5 years away from that
i'm trying to imagine what he would write
on the board
"wait, can i look at stack overflow?"
lol
i wish i had saved the conversations i had with him back in the day
lol
yea
like "why did you paste an entire tic-tac-toe game into your simon game?"
because I wanted the pop-up on the page
:joy:
1kyu lol
such intelligence
much art
wow
@thekholm80 hmm i must be missing something. Went through and deployed but it's not working. Do I need firebase database features if I'm not using a database?
i've never used the database
do you have a link to your new page?
ah looks like i have to create a production build
yeah, if you're using webpack make sure you build before you deploy
the treasure hunt of being a new dev. Pieces of helpful info scattered all over the web =)
haha
but never in one place lol
fortunately React is popular enough now that there's lots of help available
when i get stuck i just ask @Manish-Giri
definitely. The docs and forums are awesome.
they have a discord for react devs too, that's super helpful
@Manish-Giri @thekholm80 I know you're way past this but this was my js solution - any way to make it better?
let isPangram=(s)=>!(new Set(s.replace(/[^a-z]/ig, '')).size < 26)

ah didn't see his answer
I sure don't miss all that type declaring in Java

@DarrenfJ I don't think they like the chat room any more, seems like they would prefer people use the forums, but I don't know why both can't be supported
got it (still used regex lol
@cmccormack @DarrenfJ i actully met Quincy not long ago :) and yes he said gitter is pretty much abandonware :(
Would be great if we could move everything to Slack or Discord if that's the stance, Forums aren't nearly the same experience
he said discord is more gaming oriented
because it was made more for gaming then for programming or somthing like that
he said slack is not good for large groups
Was a a fcc meetup, he was there to talk about new stuff coming
Anything good?
Yes
pretty much redoing everything
those of us that have certificates can continue working on our certificates
but full stack will now require 6 certificates
but the requirement of then will be 5 projects
but you no longer have to do 800 hours of open source work
which he said no one has done because onlyone who comes close gets a job
Yup that makes sense haha
um
fata visualization will stay i think
front and and back end being split up
and a algorithm certificate
eventually there will be many many algoriths you can do to learn
not for certificate
also their own version of mdn
that is beginner friendly
when is this going to be up?
no date
said theyve missed to many dates before
sorry about typos
the algorithm and mdn thing are a "eventually" type thing
the new certificates are coming tho
oh and no one after dec 31 of this year will be able to get the current front end and back end certificates
but we will keep ours
verified link will remain
I better get my backend done then!
No rush
I think
as long as your account
was made before dec 31st*
that's good to hear
i'm having trouble motivating myself to finish my last projects
i'm having trouble motivating myself to finish my last projects

yah.. most of this is part of the beta post in the forum.. which most of us over here hate to go into, ironically
hello everyone !
@Gersho buddy!
but the good news is we all get the old certs if we finish them off
which was really one of the tings i waiting out.. the new certs
but now shrug why wait

yah.. i like algo challenges like codewars and hackerrank now.. still working through the intro stuff from Hackreactor too
the more i learn about react the more i feel i lost my time learning jquery

learn java

The replacement string can include the following special replacement patterns:
Pattern Inserts
$$ Inserts a "$".
$& Inserts the matched substring.
$` Inserts the portion of the string that precedes the matched substring.
$' Inserts the portion of the string that follows the matched substring.
$n Where n is a positive integer less than 100, inserts the nth parenthesized submatch string, provided the first argument was a RegExp object. Note that this is 1-indexed.is the exact same text from the doc
