Benchmark: .map vs for loop vs for loop cached vs for of

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 = []; for (let i=0; i<array.length; i++) { newArray.push(manipulateFn(array[i])); }
for loop cached
var newArray = []; const arrayLength = array.length; for (let i=0; i<arrayLength; i++) { newArray.push(manipulateFn(array[i])); }
for of
var newArray = []; for (let value of array) { newArray.push(manipulateFn(value)); }
