@longnt80 thanks for the reply. SCSS compiles successfully when I use Atom instead of VSCode. From what I've read, my best guess is that my hard drive is slow at writing, so while the scss file is being saved, the scss file is inaccessible, resulting in a failure to be compiled. I think Atom works bc it has a different saving method than VSCode. I think the solution is to edit chokidar(?) to wait temporarily until the file is done being saved before processing it.

That was the solution I found on StackOverflow and from node-sass github page
How much should i charge for 2 construction companies ....looking for a rough ballpark estimate of cost. All pics, writing and info has already been put together and will be provided before commencement of work. The websites would consist of main page, about us page, contact us page and a few pages with different categories & pics and testimonials from customers
why the pictures in the codepen on google can not display?
on googlechrome broswer
@phoenix-burn hourly rate * time spent
What would someone charge to add 200 products into WooCommerce?
@phoenix-burn if you settle for fixed price, you'll end up in endless loop of revisions
@MikeJSchorah There is no option to import products to Woocommerce?
Hey guys im trying to change the color of an input's outline when you're focused on it and also add a transition. Can't figure out why it turns black before turning yellow
https://codepen.io/kbaig/pen/jGjvaQ?editors=1100
https://codepen.io/kbaig/pen/jGjvaQ?editors=1100
@kbaig you need also target input:hover
@korzo huh. why is that?
@kbaig because black is default color
@korzo I guess I'm just confused as to why there's a default hover outline to begin with
@korzo What exactly do you mean by "import products"? Does this save alot of time?
@korzo oh well, thanks!
kbaig sends brownie points to @korzo :sparkles: :thumbsup: :sparkles:
:cookie: 661 | @korzo |http://www.freecodecamp.com/korzo
@kbaig best way is to define outline color and with 0 for input and then change width for focus/active/hover
@MikeJSchorah Yes, especially if you have some source of products (information system, feed from supplier..)
If not, it's faster to write data in excel and import it then fill every product then save
If not, it's faster to write data in excel and import it then fill every product then save
I don't use WooCommerce so I don't know thou @MikeJSchorah
Does anyone here use WooCommerce?

@Manish-Giri why not the number in that position bro
?
um, coz that's the way
.push() has been written - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/push?v=b
Return value
The new length property of the object upon which the method was called.
@Manish-Giri hmmm what do you suggest to use to push the arr[][]
you can just delete the
return
rest of the code in that line will push
@Manish-Giri its nor returning anything
whatever you want your function to
return, should be the very last line in your function, because anything below the return won't execute
so put your
return statement on line 7
have a look
if you instead want to see the current state of your variables, i'd recommend using a
console.log statement
that link won't have your code
maybe use this - https://jsbin.com/?js,console
it's easier to write, test and share code here
@Manish-Giri got it bro !!!!!! thanks!!!!!!!!!!!!!!!!!!

Any JavaScript developer please help me to understand this bit of code
function Employee() {
......
}
function WorkerBee() {
.......
}
// Situation 1
WorkerBee.prototype = new Employee();
// Situation 2
WorkerBee.prototype = Object.create(Employee.prototype);Does situation 1 and situation 2 are creating the same object?
hello world im back
need help
the rest of the numbers are ok
but this particular one is giving me a null
hello universe!!!
:cry:
@gishy1 Do you ever reset New back to 0 ?
@iAziz786 I don't believe there is any difference between the two
@gishy1 have you thought about doing a
.forEach() instead of using for loops?
@rscales02 or he could just map and Math.max(...elem)
@gishy1 , @kbaig has a better way than mine...
why is there no difference between strong and em when i run this in jsfiddle?
<p>Here is some text html in which will be present both the <strong>strong</strong> tags and the <em>em</em> tags.</p>
@bilaal-s it seems with jsfiddle you need to define the css for those tags...
it renders just fine in codepen without styling...https://codepen.io/rscales02/pen/oGKjLJ
@rscales02 think in jsfiddle its just a render problem. i associate <strong> with bold and <i>,<em> with italic
@rscales02 if you look in devtools you will see that the word strong has
font-weight: bold; and em font-style: italic;
@rscales02 you can read more about this tags on MDN here
@sorinr that was what I was alluding to, although as soon as you define the css in jsfiddle it renders out like it should...
@rscales02 yep. seen this strange behaviour
@rscales02 no idea why renders like that
that makes 2 of us... I'm not really a huge fan of the fiddle from my use of it so far anyway
me neither
@sjames1958gm I also think so.

help please
@sjames1958gm james should i set to 0 tho? what would be the rationale mate?
@gishy1 You want to find the largest of each set of 4 you need to reset it to a low value for each inner array
@sjames1958gm also could that be the reason its giving me a null value?
@sjames1958gm how do you suggest i reset ?
@gishy1 Yes. Because no value in the second array is larger than New you never set that value
New = 0 either before or after the inner loop
@muchristian Do you have the android ADK downloaded?
@sjames1958gm yes mate that worked!!! but iim still trying to understand the rationale for it being in between the loops
@gishy1 Each group is independent, so you need to reset "New" which is supposed to be lower than all values for each new set of 4

@sarthak0411 you mean to be accessible from outside?
Heyo!
@dsandeepchary :wave:
@sorinr yes
I remember you @sjames1958gm
:wave:
@sarthak0411 are your apache server under a router? do u have a fixed IP?
Yes i have fixed ip @sorinr
@sarthak0411 then go to the router and instruct it for any calls on port 80 to forward your calls to the machine ip thats running the apache server
After that @sorinr
@sarthak0411 if i write your ip xx.xxx.xxx in the browser bar it should redirect me to your apache server and see the index.html/index.php page you have in there

@Emgo-Dev - a Pull request is related to github, - you can read the docs here: https://help.github.com/articles/about-pull-requests/ (I didn't notice the previous post from @kbaig)...
I'n a local configuration with create-react-app I can't apply a style by selecting an "h1" as it is. But I can apply the style if I assign an idea to the h1 and then select the h1 by id in the css file. Anyone has an idea why this could happen?
id* not idea
Example:
Doesn't work ->
html:
<h1 id="hStyle"> Heading </h1>
css:
h1{
color:red;
}
Works ->
html:
<h1 id="hStyle"> Heading </h1>
css:
#hStyle{
color:red;
}
@artbohr So if you init a new app, add an
h1 element to the component in App.js, and add an h1 rule in index.css, does it not work?
Trying to come up with a minimum working example here since I don't have the code
render() {
return (
<Grid>
<h1 id="titleText">{`${this.state.showing === "recent"
? "Recent"
: "Alltime"} Campers Leaderboard`}</h1>
<Button id="switchButton" bsStyle="default" onClick={this.switchBoard}>
Switch Leaderboard
</Button>
<CamperTable camplist={this.state[this.state.showing]}/>
</Grid>
);
}
}
@kbaig here is the exact code
@kbaig applying styles just by selecting h1 instead of id or class just gets ignored
@artbohr I don't think you're supposed to nest elements within components. I think components are always supposed to be self-closing
@kbaig maybe you are confusing components with react-bootstrap lib? Or I'm understanding something wrong here
@artbohr check the devtools for if the color gets overridden by another rule. h1 is very generic as selecor whereas #something is much more specific and can override more general selectors.
I am not talking about bootstrap
I am saying React components always have to be self-closing if I am not mistaken
@kbaig what do you mean by self-closing? If you cannot nest components in components, the components would not make sense
Oh is
Grid a boostrap component
:D
<SelfClosingElement/><NotSelfClosingElem></NotSelfClosingElem>
@artbohr https://www.smashingmagazine.com/2007/07/css-specificity-things-you-should-know/ maybe gives you some understanding of what could have happened
@kbaig makes no difference in react as well as in html
@alpox it works in codepen but not in local setup
@artbohr you might have something slightly different in the local setup
Maybe a different order of the css rules?
@kbaig ye you could nest child element there and call them with "this.props.children", check this for an example with the new react 16 and portals "https://codepen.io/gaearon/pen/yzMaBd?editors=0010"
elements*
@alpox btw, in terms of end results it doesn't even matter, I just wanted to get rid of additional classes/ids since there is only one H1 and Button, or is it okay to apply extra ids/classes where is not stricly neccesary?
@alpox also, I can't find the css rules, I think create-react-app project hide most configs, if I'm not mistaken
@alpox or you mean css rules in the dev tools?
@artbohr ah I didn't know about portals. Is that new? Looks super interesting
@kbaig ye, about a month or so
@artbohr oh react 16
@alpox @kbaig I found the reason I think, it's because some bootstrap config overrides it, for being very generic, you can take command with "!important" tho, if you really need it
h1{
color:red !important;
}thank you ^^

@artbohr Oh so you were using bootsrap. Gotcha. Gotta be it then
@artbohr It depends on the size of the project. But i would always go for being as specific as you need to be. This means that you evaluate things like:
Does the style apply to all h1 on the page? Does it only apply to h1 in a specific section or elements which are related to some parent in some way? Does it really only always apply to only one h1 element?
Does the style apply to all h1 on the page? Does it only apply to h1 in a specific section or elements which are related to some parent in some way? Does it really only always apply to only one h1 element?
Thats the kind of questions you ask before choosing a selector
@artbohr Yes thats what i thought it would be. Thats why i said an id could work instead of
h1 because the id is less general. - The article i sent you tells you how the specificy is calculated - so it tells you how specific the selector has to be to override other rules
@alpox ye, scalability and structure, but for this exact project it was only 2 items, and no shared parents or children or element of any kind and place
@artbohr
!important should only be used if you have absolutely no other choice - or for strict utility classes
@alpox ok, it totally sounds like you shouldn't use it in a lot of cases tbh :D
@sjames1958gm need help take a look
@gishy1 you are comparing a single letter, but target can be more than one letter.
You need to figure out how to extract target.length string from end of str
You need to figure out how to extract target.length string from end of str
@sjames1958gm i tried to use substring(str.length-4,str.length-1)
didnt work out
never returned anything when i tested
i had created another variable to store the substring then used the logical operator
let me show you
@gishy1 You should be using target.length and your second parameter is off by one
Optional. An integer between 0 and the length of the string, which specifies the offset into the string of the first character
Optional. An integer between 0 and the length of the string, which specifies the offset into the string of the first character
not to include in the returned substring.
The second parameter is not needed to go to end of string.
@sjames1958gm mind is in a twist
substring(str.length-4,str.length-1) the 4 here should be target.length so that any target will work.str.length-1 will not include the last character.
substring(str.length - target.length)
@sjames1958gm mate check this
its giving me the last 2 words of the string for target.length
@gishy1 The -1 will skip the last letter
@sjames1958gm but i thought index cound starts from 0?
how to make the background of a div one colour all the height and width and not only the container in bootstrap?
@gishy1 If you want the last letter and target.length is 1
substring(string.length - target.length) is the same as
substring(string.length - 1)
so you don't need string.length - 1- target.length
substring(string.length - target.length) is the same as
substring(string.length - 1)
so you don't need string.length - 1- target.length
var d = substring(str.length - target.length)should be enough
@sjames1958gm wait target length is 1 ?
It's just am example of why the -1 is not needed.
@sjames1958gm this is going to wind you up mate but bear with me
i thought we start counting from 0
no?
@gishy1 Yes. so if target and str are the name length.
substring(str.length - target.length) is the same as substring(0)
substring(str.length - target.length) is the same as substring(0)
@sjames1958gm also should i remove the spaces with regex
You should not remove anything.

I got a question, I am still stuck on this I even tried it with for loops but now I am just feeling slow so maybe you can help or see what I am not doing that I need to add
function truthCheck(collection, pre) {
let x = Object.keys(arguments[0]).every(function(key) {
//console.log(collection[k])
console.log(key)
if (!arguments[0].hasOwnProperty(pre)) {
return false;
} else {
return true;
}
});
console.log(x);
// Only change code above this line
return x;
}
I can't get it to return the true portion
I also did this with collection
@daddycardona challenge URL?
function truthCheck(collection, pre) {
let x = Object.keys(collection[0]).every(function(key) {
//console.log(collection[k])
console.log(key);
if (!collection[0].hasOwnProperty(pre) && !collection[0][key]) {
return false;
}
});
console.log(x);
// Only change code above this line
return x;
}
should I take the
[0] out of collection I think I done that already
function spinalCase(str) {
// "It's such a fine line between stupid, and clever."
// --David St. Hubbins
str = str.replace(/[^a-z\A-Z]/g, "-");
console.log(str);
var newStr = str.toLowerCase();
return newStr;
}
spinalCase('AllThe-small Things');Hey, guys. How can I insert a dash every time a lowercase letter is proceded by an uppercase? Can't figure it out.
This returns allthe-small-things
@daddycardona you need to change this
if (!collection[0].hasOwnProperty(pre) && !collection[0][key]) {
return false;
}
in fact, instead of going for
Object.keys()
you know what now that I got some much needed sleep I see that :)
go for
collection.every()
@Burinson you can use a regex to check for a lookahead
It don't recognize this condition I was like why is it always true or always false lol
thanks @Manish-Giri you are a guru :)
daddycardona sends brownie points to @manish-giri :sparkles: :thumbsup: :sparkles:
api offline
lol
haha
@Manish-Giri Hm... that one is new to me, lol
str = str.replace(/[^a-z\A-Z(?=A-Z)]/g, "-"); How should the syntax go?
so basically do I need a conditional statement in every. It should return true or false, should I just be like
return collection.hasOwnProperty(pre)
@Burinson
/[a-z](?=[A-Z])/g
this will match the
d in - abcdAe
@daddycardona you need just a
&& in .every
collection.every(c => /* check if c hasOwnProperty of pre and c[pre] is truthy */)
that's all
&& collection[pre]
oh okay because c[pre] mean collection.age or the condtion its lookin for okay
yup
collection is an array of objects
so
collection.every(c => ), here c will be each individual object
on which you can do
c.hasOwnProperty() or c.age, etc
yed
@Manish-Giri When it matches the d, it would replace the d, right?
@Manish-Giri teach me javascript
@GitHub-Henry Hi
pfffffft
So instead of
abcd-A it would return abc-A?
Hi guys need some help, my js function fails to concatenate the url from the object with my value from getElementById and I don't know why(line 30)
https://jsfiddle.net/4mLn5h77/
https://jsfiddle.net/4mLn5h77/
it conctenates just the "+"
@Burinson yes
function testLookAhead(str) {
return str.replace(/[a-z](?=[A-Z])/g, '-');
}
console.log(testLookAhead("helloWorld"));"hell-World"
How could we make your code say "hello-World"?
@victorja You have to call event.preventDefault(), otherwise page reload every time, you click submit button
@Burinson for that you use a "capturing group"
function testLookAhead(str) {
return str.replace(/([a-z](?=[A-Z]))/g, '$1-');
}
now the output is
"hello-World"
so when using every it takes the array out of it and makes sure it is not an array just looks through the objecst like a
for loop using collection[0] instead i will just use the the c or in my case the word key because that becomes the actual object and every already started the loop. Methods are so amazing when you really start understanding them. I see instead of collection.hasOwnProperty it should bekey.hasOwnProperty because it is the object and is looking for thru the object of key. Damn you're such a great teacher @Manish-Giri thanks for clearing that up for me took me some time to get it ;)

@Burinson
var newStr = str.replace(/\s+|_+/g, '-'); After what you told me, I just put this and it worked
nice
@Burinson that is good I am still confused with regex
now I am on the very next assignment for free codecamp and the whole thing is confusing lol
regex is horrible
@victorja Because of the nature of jsfiddle, I am not sure you can call the getSubmit function from the input element like that
as the javascript is wrapped in a window.onload=function() {} so it is not in scope.
You might want to use
as the javascript is wrapped in a window.onload=function() {} so it is not in scope.
You might want to use
element.addEventListener("click", getSubmit);
@daddycardona arguments optional?
yes @sjames1958gm the whole explanation is confusing and I was under the impression you not suppose to call on something with arguments that have none
this is very new to me lol
@daddycardona Have you done seek and destroy? Using arguments object?
I don't know let me check that out
yes i did unfortunately it is not there to see what I have done lol
freaking FCC
why did they make it so you can't access
arguments in an arrow function?
stupid js
@daddycardona In js you can call functions with more or less arguments than defined.
You have to use arguments object to determine how many were passed in argument.length
Then you can test if the ones passed are numbers

@thekholm80 arrow functions are supposed to be light weight.
they should be light-weight with access to arguments
@thekholm80 You can use rest syntax in parameter
@daddycardona It is confusing :(, but you'll get it. I was once stuck trying to understand for loops for like 4 weeks, lol
@Burinson I feel you wait to you start using the methods like reduce and map. I need to code everyday and use these things but once I start using them then I have to start using react. I see so many places using react and php it is like very confusing and then to get a job in that lol
Imo you should take things slow
Get comfy with the language itself first
Then you can pick up react easily
I didn't really understand javascript at all until i started learning react
but it was definitely a 'sink-or-swim' kind of experience
I don't even know what is react
I'm halfway done with intermediate algorithms tho
@thekholm80 yest I bought stevie g’s graphql course
@Manish-Giri Stephen Grider?
And a course on Golang
@Manish-Giri you'll have to let me know how it is
@sjames1958gm yup
I hope he's stopped smacking his lips in the mic by now lol
There’s a course on web dev using Go that I’ll get, after finishing the basic Go course
@Manish-Giri I am doing his react native course and bought his full stack server rendered react course
Grider too has a course on Go
@Manish-Giri He covers a lot, a bit slowly at times.
@sjames1958gm i finished his basic react-redux course last week, the advanced one is up next
i liked his redux course
so you use what @Manish-Giri
web dev is that a site?
Um
It’s just short for web development
@daddycardona
yes I thought that was a site that you got that you bought the course from
Oh that
Yeah it’s on udemy.com
@daddycardona Part of the challenge of coding is taking the instructions and organizing them in a logic fashion even if the instructions are haphazard.
Find the major decision points, such as one argument or two
Find the major decision points, such as one argument or two
They have good courses on almost everything
@daddycardona
@Manish-Giri I was on their early access - review program - there are some bad ones as well.
I even review a course by a kid on how to fish.
I even review a course by a kid on how to fish.
and never pay full price @daddycardona unless you have no other choice
@thekholm80 :+1: I don't think I have paid more than $20
most udemy stuff goes on sale for $10 all the time
@sjames1958gm I’m on their early access program too, but I’ve never actually reviewed anything yet
nice :) I am thinking about starting treehouse but am waiting for someone to call me about a school for electronic tech stuff and have my GI bill pay for it and hopefully land a job doing something like that and have the time to study this too for this is my passion and this is the closest I have been to it ;)
Gotta do one sometime
@daddycardona :+1: Passion will get you through the tough times learning to code.
that is why I have not quit yet lol
I have stopped many times with being in the military and having kids and then going to college that tought me the same basics of programming I already knew in Java lol
and then if you did not understand something stackoverflow is there to answer the questions LOL
There are tons more resources for learning than just a few years ago, almost too many.
that is why I am interested in Treehouse, they seem to have alot to help according to their site also mentors people like you guys but can give me a one on one with
I wish there was a classroom-type option between bootcamps and college. more in-depth, but not so heavy on theory
yes I feel you @thekholm80 college is like learn this shit learn math there you go, unless it's a intro class and they want you to answer useless questions like what year was javacsctript was introduced and what was its first name. Um not important though I read it in this book and know it was like 90's or something lol
Netscape yeah yeah lol
@daddycardona right? I think it's awesome to know the different sorting algorithms but then again, i prefer to just use
sort()
can't recall the last time i wrote a bubble sort algo for anything besides a demo
lol what is a bubble sort lol
a type of sorting algorithm
it's actually really fascinating but you'd likely never use the information
Sorting sucks
Especially when you need to write it in an interview
Quick sort, merge sort, shell sort
i am a believer of learning stuff that is is going to help you in real life scenarios, i understand hello world intros and the basics in general but show me how the general basic stuff is going to be used on an every day website for instance :)
Selection sort, insertion sort, bubble sort
there are a bunch of videos like this one that do a good job of explaining how the different sort algos work without getting all bogged down in code
wow I never saw this before my colleges suck lol jk
there's a free CS50 course you can do from Harvard that covers a lot of the basic theory
the guy that teaches it is awesome
but it's not a lot of practical information
the thing is that some of this is very easy and then you use it for something else and the one thing you do know is not even practical or efficient like it use to be lol
and everytime i learn something and use it and go to stack overflow they are like why you doing it like that, that way sucks lol
Not sure why so many people have to be dicks on SO
part of being so much smarter than everyone else is making sure everyone knows it
I don't think they want to be dicks @sjames1958gm but they be forgetting that there is stuff they don't know and is confusing to them lol
the best way to get a good answer on SO is to either
- pretend you're a girl
- log in with another account and give a wrong answer
lmao
Method 1 always works
