Benchmark: test spread vs foreach array

Script Preparation code:

var arr1 = ['a', 'b', 'c'];
var arr2 = ['aa', 'bb', 'cc'];
var arr3 = ['aaa', 'bbb', 'ccc'];
var arr4 = ['aaaa', 'bbbb', 'cccc'];
var arr5 = ['aaaaa', 'bbbbb', 'ccccc'];

Tests:

array spread
var result = [...arr1, ...arr2, ...arr3, ...arr4, ...arr5];
forEach
var result = []; arr1.forEach(r => result.push(r)) arr2.forEach(r => result.push(r)) arr3.forEach(r => result.push(r)) arr4.forEach(r => result.push(r)) arr5.forEach(r => result.push(r))
