Benchmark: for loop vs. .map anon2

Script Preparation code:

// Create sample data
var array = [1,2,3,4,5,6,7,8,9,0];
for (let i = 0; i< 100_000; i++) {
	array.push(i % 10);
}

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(i *2 * 3); }
for loop with func
var newArray = []; for (let i=0; i<array.length; i++) { newArray.push(manipulateFn(i)); }
