Benchmark: concatenating 2 arrays

Tests:

push apply
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] Array.prototype.push.apply(arr2, arr)
push spread
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] arr2.push(...arr)
concat
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] arr2 = arr2.concat(arr)
for push
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] for(var i = 0, len = arr.length; i < len; i++) { arr2.push(arr[i]) }
for of push
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] for(var item of arr) { arr2.push(item) }
forEach push
var arr = [1,2,3,4,5,6,7,8,9,10] var arr2 = [] arr.forEach(function(item) { arr2.push(item) })
