You need to use the forEach method on the numbers variable, and then use the push method to add the new value to the times10 array as below:

const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [];

// times10 should be: [10,20,30,40,50,60,70,80,90,100]
// Write your code below

numbers.forEach(function(number) {
  times10.push(number * 10); 
}); 

hope that helps!

Very close. All you have to do is use map instead of forEach.

const numbers = [1,2,3,4,5,6,7,8,9,10];
const times10 = numbers.map( number => number * 10);

Sorry, didn't read the actual question being asked by treehouse. The answer by Milan Pankhania fits the criteria better for how they want you to solve it. Using map is the proper way outside of learning the forEach method.
