4,283 PointsWhere did I go wrong? For each array
Please help
const numbers = [1,2,3,4,5,6,7,8,9,10];
let times5 = [];
// times5 should be: [5,10,15,20,25,30,35,40,45,50]
// Write your code below
numbers.forEach(function(){
times5 = numbers * 5;
});

11,820 PointsHi Kiara,
The function inside forEach needs a parameter. You can name it anything you like, it will represent the individual items inside the array. From there you will want to add them one at a time to the the times5 array which you can do using the .push method:
numbers.forEach( function(item) {
times5.push(item*5);
});
Hope this helps! Let me know if you have any questions.

4,283 PointsOh, interesting! I thought you could only use .push to add items to the end of an existing array (with values). I never thought about using it in an empty array! Thanks for the advice!
Kiara Stewart
4,283 PointsSo if I rewrote this in arrow for it would be -
numbers.forEach( item => times5.push(item*5));
Cameron Childres
11,820 PointsExactly, you got it!

const numbers = [1,2,3,4,5,6,7,8,9,10]; let times5 = []; // times5 should be: [5,10,15,20,25,30,35,40,45,50] // Write your code below numbers.forEach(num => num * 5);
