Benchmark: for vs foreach vs for..of vs for..of over entries with big number of elements

Script Preparation code:

var array = Array.from({length: 5000});
var t;

Tests:

for
var len = array.length; for (let i = 0; i < len; i++) { t = array[i]; }
foreach
array.forEach(function(v, i) { t = v; });
for..of
for (var v of array) { t = v; }
for..of over entries
for (var [i, v] of array.entries()) { t = v; }
