Benchmark: String() vs .toString() vs `${num}` vs ("" +) vs (+ "")

Tests:

String()
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(String(num)); }
.toString()
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(num.toString()); }
`${num}`
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(`${num}`); }
"" + num
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push("" + num); }
num + ""
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(num + ""); }
