Benchmark: array string for vs foreach vs for..in vs for..of

Script Preparation code:

var array = new Array('1','2','3','4','5','1','2','3','4','5','1','2','3','4','5','1','2','3','4','5','1','2','3','4','5','1','2','3','4','5','1','2','3','4','5','1','2','3','4','5',);

Tests:

for
for (var i = 0; i < array.length; i++) { array[i]; }
foreach
array.forEach(function(i) { array[i]; });
for in
for (var i in array) { array[i]; }
for..of
for (var i of array) { array[i]; }
