Benchmark: for vs foreach vs some vs for..of (string array of alphabet; doing actual work)

Script Preparation code:

var array = ["a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z"];

Tests:

for
let result = ""; for (var i = 0; i < array.length; i++) { result = result + array[i]; }
foreach
let result = ""; array.forEach(function(element) { result = result + element; });
some
array.some(function(element) { return element === "z"; });
for..of
let result = ""; for (var element of array) { result = result + element; }
