Js - The other example of difference between .map() and .filter()

 function double (number) { return number*2;}

const numbers = [5, 2, 7, 6];

const doubled = numbers.map(double);

console.log(doubled);

VM2529:1 (4) [10, 4, 14, 12]

const test2 = numbers.filter(double);

console.log(test2);

VM2721:1 (4) [5, 2, 7, 6]

Here what gonna work is the map that what do is apply the rule for each example, and the other how isn't a test would not change nothing, so the filter you see that make an Boolean test, how I didn't make a comparison just did nothing.
