Benchmark: push vs set length and index

Tests:

push
const arr = [] const length = 100000 for(let i = 0; i < length; i++) { arr.push(i, 1) } console.log(arr[0], arr[100], arr[1000], arr[10001], arr[20000])
index
const arr = [] const length = 100000 arr.length = length*2+1 for(let i = 0; i < length; i++) { arr[i*2] = i; arr[i*2+1] = 1; } console.log(arr[0], arr[100], arr[1000], arr[10001], arr[20000])
