Benchmark: for vs backwards for vs foreach vs for..of with loop content

Script Preparation code:

var array = new Array(100);

Tests:

for
for (var i = 0; i < array.length; i++) { array[i] = Date.now(); }
foreach
array.forEach(function(i) { array[i] = Date.now(); });
for..of
for (var i of array) { array[i] = Date.now(); }
backwards for
for (var i = array.length-1; i >=0; --i) { array[i] = Date.now(); }
