assign map function to an array code example

Example 1: how the map function works javascript

const array = [2, 5, 9];
let squares = array.map((num) => num * num);

console.log(array); // [2, 5, 9]
console.log(squares); // [4, 25, 81]

const exampleArray = ['aa','bbc','ccdd'];
console.log(exampleArray.map(a => a.length));
