Benchmark: 3 different for loops vs foreach() vs some() (fixed)

Script Preparation code:

var array = [];
var i = 0;
for (; i < 1000; ++i) {
 	array[i] = 1;
}

Tests:

for (dynamic length)
var i = 0; for (; i < array.length; ++i) { array[i] = 1 - array[i]; }
foreach
array.forEach(function(num, i) { array[i] = 1 - num; });
some
array.some(function(num, i) { array[i] = 1 - num; });
for (static length)
var len = array.length var i = 0; for (; i < len; ++i) { array[i] = 1 - array[i]; }
backward for
var i = array.length - 1 for (; i >= 0; --i) { array[i] = 1 - array[i]; }
