Beginner - Lost Without a Map.js

// Given an array of integers, return a new array with each value doubled.

// For example:

// [1, 2, 3] --> [2, 4, 6]

function maps(x){
    let x1= x.map(element=>element*2)
    return x1;
  }
  console.log(maps([1, 2, 3]), [2, 4, 6])
  console.log(maps([4, 1, 1, 1, 4]), [8, 2, 2, 2, 8])
