Script Preparation code:

// Create sample data
const array = Array.from({ length: 100000 }, () => Math.floor(Math.random() * 1_000_000));

var manipulateFn = num => {
	return num * 2 * 3;
}

Tests:

.map
var newArray = array.map( i => manipulateFn(i));
for loop
var newArray = []; for (let i=0; i<array.length; i++) { newArray.push(manipulateFn(array[i])); }
