can anyone help me ,

Using forEach, iterate over the numbers array and multiply each number by 10, storing these new numbers in the times10 array.

app.js 
const numbers = [1,2,3,4,5,6,7,8,9,10];
let times10 = [numbers.forEach(function(numbers){
    times10.push(numbers * 5)
})];

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

You have the right idea, but have a few issues yet:

  • don't replace the code above the comment, add all your code below the "Write your code below" line
  • the "push" will fill up the array, you won't need a separate assignment
  • the instructions say "multiply each number by 10", but this code is multiplying by 5 instead
