Script Preparation code:

var array = new Array(100);
for (let i = 0, end = array.length; i < end; i += 1) {
  array[i] = i;
}

Tests:

for
let sum = 0; for (var i = 0; i < array.length; i += 1) { sum += array[i]; }
foreach
let sum = 0; array.forEach(function(i) { sum += array[i]; });
some
let sum = 0; array.some(function(i) { sum += array[i]; });
for..of
let sum = 0; for (var i of array) { sum += array[i]; }
for with cached length
let sum = 0; for (var i = 0, end = array.length; i < end; i += 1) { sum += array[i]; }
