Benchmark: For Loops Teflora Test

Script Preparation code:

var numbers = [];
for(var i = 0; i < 10000; ++i)
  numbers[i] = Math.random();

Tests:

for loop i++
for(var i = 0; i < numbers.length; i++) numbers[i] = numbers[i] * 1.5;
for loop ++i
for(var i = 0; i < numbers.length; ++i) numbers[i] = numbers[i] * 1.5;
for loop ++i, cached length
const length = numbers.length; for(var i = 0; i < length; i++) numbers[i] = numbers[i] * 1.5;
while i--
var i = numbers.length; while(i--) numbers[i] = numbers[i] * 1.5;
while ++i
var i = -numbers.length; while(++i) numbers[-i] = numbers[-i] * 1.5;
