const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34];
const squareList = (arr) => {
"use strict";
function inter (int) {
return int.isInteger;
};
const squaredIntegers = realNumberArray.filter(inter);
I don't know why this don't return an array of Int...
someone can help me?
isInteger exists only on the Number constructor
but in FCC don't
const realNumberArray = [4, 5.6, -9.8, 3.14, 42, 6, 8.34];
const squareList = (arr) => {
"use strict";
// change code below this line
function inter (int) {
return Number.isInteger();
};
const a = realNumberArray.filter(inter);
const squaredIntegers = a.map(val => Math.pow(val, 2));
// change code above this line
return squaredIntegers;
};
function inter (int) {
return Number.isInteger(); /// u not passing anything to that function
};
const a = realNumberArray.filter(inter);http://mdn.io/isinteger

now yes, but it's still the same
now
@AlbertoGiambone Number.isInteger(realNumberArray); the argument passed is..wrong. The usage of isInteger is Number.isInteger(num) so for example
Number.isInteger(1.2) //false
Number.isInteger(3) //trueYou're passing array instead, also you should look up documentation of .filter() and what parameters the callback function takes.
Hello... can anyone help me understand why my image isn't displaying for my Twitch Viewer app?
I actually completed this challenge about a year ago and it was working fine, but when I checked on it last week, I noticed the stream logo/image was not displaying. Everything else does, but not the image. I can't figure out why. I thought that perhaps the link to the image was broken, but I created another pen to test it, and it worked perfectly fine.
Can anyone please help me figure out what's wrong?
The first challenge in SASS says to create a variable and assign it to the color property of the .blog-post class and h2 element, after doing this and getting the desired results on the screen the challenge says I need to "Your .blog-post element should have a </code>color</code> of red.
Your h2 elements should have a </code>color</code> of red."
Not sure what to do to make this work, here is the code
<style type='text/sass'>
$text-color:red;
.blog-post, h2 {
color: $text-color;
}
</style>
toggleClass. If you turn the game on and hit Strict mode, you will see that the class is being toggled on and off, but nothing is actually happening to my indicator above the button, which should turn red or black alternately when the button is clicked. I have a general .red-indicator css class that has a red background-color, but it isn't being applied. Any ideas why this isn't working?
!important to your red indicator and it will work - background-color: rgb(255,0,0) !important;
