Test name	Executions per second
.map	4332702.0 Ops/sec
for loop	7568896.0 Ops/sec

Script Preparation code:

// Create sample data
var array = [1,2,3,4,5,6,7,8,9,0];

var manipulateFn = num => {
	return num * 2 * 3;
}

Tests:

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