Benchmark: js array copy speed comparison - spread - push

Tests:

map
const arr = [1,2,3,4,5] const newArr = arr.map(e=>e)
array.from
const arr = [1,2,3,4,5] const newArr = Array.from(arr)
for loop
const arr = [1,2,3,4,5] let newArr = []; for(let i = 0; i < arr.length; i++) { newArr[i] = arr[i]; }
foreach
const arr = [1,2,3,4,5] let newArr = [] arr.forEach(e => { newArr.push(e) })
slice
const arr = [1,2,3,4,5] const newArr = arr.slice()
spread
const arr = [1,2,3,4,5] const newArr = [...arr]
push
const arr = [1,2,3,4,5] const newArr = [] for(let i = 0; i < arr.length; ++i) newArr.push(arr[i])
