Script Preparation code:
var arr = []; for (var i = 0; i < 1000; i++) { arr[i] = i; } function someFn(i) { return i * 3 * 8; }
Tests:
foreach
arr.forEach(function (item){ someFn(item); })
for
for (var i = 0, len = arr.length; i < len; i++) { someFn(arr[i]); }
map
arr.map(item => someFn(item))
filter
arr.filter(item => someFn(item))
reduce
arr.reduce(item => someFn(item))
