Benchmark: var vs let vs const performace4

Tests:

Var
const nums = [55, 21, 807, 41, 56, 66, 202]; for(var x = 0, l = nums.length; x < l; ++x) {var a=nums[x]; console.log(a); }
Let
const nums = [55, 21, 807, 41, 56, 66, 202]; for(let x = 0, l = nums.length; x < l; ++x) {let a=nums[x]; console.log(a); }
Const
const nums = [55, 21, 807, 41, 56, 66, 202]; for(let x = 0, l = nums.length; x < l; ++x) {const a=nums[x]; console.log(a); }
