Benchmark: reversed versus ordered (+ cached)

Script Preparation code:

var array = [];
for (let i = 0 ; i < 10000 ; i++) {
	array.push (Math.random () * 100);
}

Tests:

ordered
let sum = 0; for (let i = 0 ; i < array.length ; i++) sum += array[i];
reversed
let sum = 0; for (let i = array.length - 1 ; i >= 0 ; i--) sum += array[i];
ordered cached
let sum = 0; let length = array.length; for (let i = 0 ; i < length ; i++) sum += array[i];
