The map() method creates a new array populated with the results of calling
a provided function on every element in the calling array.
const array1 = [1, 4, 9, 16];
// pass a function to map
const map1 = array1.map(x => x * 2);
console.log(map1);
// expected output: Array [2, 8, 18, 32]Copyright © 2021 Codeinu
