I think I did it with regex
like str.replace(/([13579])([13579])/g,"$1-$2");
but if you want to do it the way you are doing it, which is fine, you can try not splicing the string but pushing the values into a new one
I will work on it. One of the most awesome/frustrating things I'm finding is the amount of ways you can solve even small problems. Thank you for your help!
push i
are [i] and [i+1] odd?
> true
push "-"
push [i+1]
> false
push [i+1]
are [i] and [i+1] odd?
> true
push "-"
push [i+1]
> false
push [i+1]
that would be an algorithm to push dashes into a new array
I see. that makes a lot of sense. @crisberrios and @terakilobyte and @FreeCodeCamp are all awesome. I think I can figure it out from here...if not, you'll see me back soon. :)
:D
spent 12 hours (on and off, not continously), debugging a missing () in an if statement. Live and learn
being able to spot errors faster is part of learning
also learning the patterns...what errors messages suggest what kind of erros
@AdventureBear took me 45 min to find missing "."s in link I cut and paste from the bootstrap page
well... one problem of JS is that doesn't throw too much information when something goes wrong
When you have time, go through "Eloquent JavaScript", it'll give you a better understanding of many aspects of the language
Also, be sure to use an editor with JSHint so you don't crack your head over a missing ;
I'm using WebStrom on the advice of @terakilobyte
but it didn't alert me to the missing ()
;)
thanks I have a PDF of hte book and just can't seem to get captivated by it.
use the online version, as you can execute and modify the examples directly from the site
js does not seem as verbose on the errors as some other languages have worked with
I bet it did alert you ;)
sometimes the way it highlights errors is very subtle
hehe I feel like it throws the same error for everything
lol
@terakilobyte if I get adventurous I'll go back adn take them out and see what it says.
here's the pen I've been working on
tedious
but learning bit by bit.
right now it's just randomizing one type of workout,
and I'm starting to calculate a "binning" function to generate different patterns
very incomplete
@AdventureBear
function fill (minSteps, maxSteps, stepSize, steps)
{
var arr = [];
var factor = (maxSteps - minSteps) / (steps - 1) ;
arr[0] = stepSize * minSteps;
arr[steps-1] = stepSize * maxSteps;
for (var i = 1 ; i < steps -1 ; i++ ) {
arr[i] = stepSize * Math.round(minSteps + i*factor);
}
return arr;
}
fill(1,10,50,10);
try it :D
Trying to figure it out, lol. So this is just ONE of the types of my patterns, right?
I pasted our notes from yesterday into a notes.txt file in my project, lol.
or does that take the pace of this bit of mess ?
if (randomEndurancePattern[0] === "Pyramid 3") {
rounds = Math.floor(parseInt(totalDist.val()) / (6 * 25));
practiceSet = randomEndurancePattern[0] + "<br /> Rounds: " + rounds + "<br />";
} else if (randomEndurancePattern[0] === "Pyramid 4") {
rounds = Math.floor(parseInt(totalDist.val()) / (10 * 25));
practiceSet = randomEndurancePattern[0] + "<br /> Rounds: " + rounds + "<br />";
} else if (randomEndurancePattern[0] === "Pyramid 5") {
rounds = Math.floor(parseInt(totalDist.val()) / (15 * 25));
if (rounds<1) {
//
}
practiceSet = randomEndurancePattern[0] + "<br /> Rounds: " + rounds + "<br />";
}
well... if else if else if else if can be replaced by a switch
the function I wrote just interpolates
right. I keep thinking way ahead and how it can be refactored
then I get mentally overwhelmed.
then I get mentally overwhelmed.
fill(1,5,50,5);
I figure as I add types of sets I can expand this array:
fill(1,5,50,5);
endurancePatterns = [["Pyramid 3", 1, 2, 3],
["Pyramid 4", 1, 2, 3, 4],
["Pyramid 5", 1, 2, 3, 4, 5]]
but I realize there are probably better ways to do it.
stepsize in your example would relate to the fixed pool size right?
stepsize in your example would relate to the fixed pool size right?
right
Thanks. I think I need a mental break. Or someone else to get inside my head for awhile.

Being John Malkovich
that's it
lost in translation
:P
hahah...yes, kind of like that!
BTW, lost in translation was a great movie. I've seen it several times
Me too, pushed me to save money and fulfill my dream of visiting Japan
so did you do it?
yes! I miss it everyday :(
what do you miss about it?
do you speak japanese?
sadly, no
well... the food
the mixture of ancestral culture with technology
the parks, temples and museums
so basically everything?
the wacky and interesting things you find on every street
:)
the sense of security
yes
basically everything
But well, I'll return someday
that's the way to think abou tit
function LongestWord(sen) {
//var re = "/([A-Z ])/ig";
//var found = sen.match(re);
var arr = sen.split(" "),
longest = arr[0];
for (i = 1; i>arr.length; i++) {
if (arr[i].length > longest.length)
{
longest = arr[i];
}
}
// code goes here
return longest;
}
returns only the first word.
any ideas? coderbyte easy...
any ideas? coderbyte easy...
i>arr.length
loop will execute only 1 time
ugh.
thanks!
better!
now I need to strip out non alphanumerics.
not sure if I should do that before the split
or while checking each word
seems like before split would be best
anyone still hanging around?
trying to get ride of any non=characters in the input sentence for the longest word challege
function LongestWord(sen) {
var re = /[^a-z]\ig;
sen = sen.replace(re,'');
I just got back
regex starts and ends with /
so it would be /[^a-z]/ig
does it need a closing / after the ig?
nope
anything after / are flags
OK
that expression will get rid of spaces too
i think i got it working
right I jsut added a space between the z and the ]
is that an ok way to do it?
/[^a-z ]/ig
yes, there is a way
\s is the expression for space
or more correctly "whitespace"
or more correctly "whitespace", which includes tabs, spaces, new lines... form feed and vertical tab
thanks, this worked:
var re = /[^a-z\s0-9]/ig;
i got dinged for a test case of two "number words" not passing, so I added the numbers
but, matching space as you did it does work, just for single space
regex is interesting but frustrating too.
that easy coderbyte only took me about 3 hours.
:)
also, instead of 0-9 you can use \d
ok, good to know, I remmeber seeing that
no shortcut to replace /[a-z]/i
sure
/[^a-z\s0-9]/ig; == /[^\w\s]/g
except \w also matches "_" (underscore)
sigh. I'll get it eventually
regex is one of the most complex skills to learn
from 1 to 100, if you are at 2, I'm mostly at 3
so don't worry :P
haha. OK, thanks.
i feel better
the worst example is the RFCxxx specification for matching an e-mail address
hi, anyone available to help with dash "esha's restaurant"?
i'm on lesson 3, checkpoint 2, where i set the media query, but it's not responding.
sure
@media (max-width 500px) {
h1 {
font-size: 50px;
margin-top: 20px;
line-height: 40px;
}
}
h1 {
font-size: 50px;
margin-top: 20px;
line-height: 40px;
}
}
use ``` before and after the code
@media (max-width 500px) {
h1 {
font-size: 50px;
margin-top: 20px;
line-height: 40px;
}
}@media (max-width 500px) {
h1 {
font-size: 50px;
margin-top: 20px;
line-height: 40px;
}
}
sorry, I've never asked for help here.
huhhh???
it should be max-width: 500px
@media (max-width 500px) {
h1 {
font-size: 50px;
margin-top: 20px;
line-height: 40px;
}
}(max-width: 500px)
var fs = require('fs');
var file = process.argv[2];
var count = 0;
fs.readFile(file, function(err, data) {
if (err) throw err;
data.toString().split('').forEach(function(x){
if (x == '\n')
count += 1;
});
});
-> 0
:rage:
global scope is a lie?????
i think when u make it toString it elminates the \n
split at newline instead. read the directions carefully, it covers that gotcha.
lineCount = str.split('\n').length-1;
LOL hacky as hell but totally works.
@teddy-error is that nodeschool?
yesm
idk I fixed it just by moving the count variable declaration inside of the readFile method
I think it has something to do with the way node manages its global stack
nice. I'm on challenge 11 of the learnyounode challenges.
it hurts my brain
damn you got ahead of me :D
im on 5.
it hurts but I love these Koan style challenges
on the command line with test assertions and stuff
@Rybar that is so clever
yeah I like them too. between those adn coderbytes it's slow goign right now.
so I entertain myself with some other fun stuff in codepen
Getting all but one correct answer on this fibonacci problem on bonfire.
The value given to the function called: 75025.
What it wants: 135721.
What I get: 60696.
What it wants: 135721.
What I get: 60696.
My code:
function sumFibs(num) {
var number = 1, oddNum = 0;
var numray = [1,1];
for(i = 1; i < num; i++){
numray.push(numray[i]+numray[i-1]);
}
for(j = 0; j< num; j++){
if(numray[j] % 2 && numray[j] < num){
oddNum += numray[j];
}
}
return oddNum;
}
sumFibs(4);
This is a Bonfire challenge, by the way.
let's see
well, fibonacci starts with 0 and 1
"The first few numbers of the Fibonacci sequence are 1, 1, 2, 3, 5..." - From the challenge. So I started it off with
[1,1]
Everything else passed, cept the last one.
can you link the challenge?
ok
<hint>that failing test is failing because the value passed in is a fibonacci number</hint>
instructions say "up to and including"
if(numray[j] % 2 && numray[j] < num){
Got it.
It just donned on me
change
if(numray[j] % 2 && numray[j] < num){ to if(numray[j] % 2 && numray[j] <= num){
how are you liking bonfire @piecedigital ?
Much better than coderbyte
anyone up that knows git?
I’m here, ask away.
