Benchmark: traditional string concat vs template string concat + array join

Script Preparation code:

const a = Math.random();
const b = Math.random();
const c = Math.random();
const d = Math.random();

const arr = [a, b, c, d];

Tests:

traditional string concat
let str = ''; for (let i = 0; i < 1000; i++) { str = a + ',' + b + ',' + c + ',' + d }
template string concat
const str = `${a},${b},${c}${d}`;
Array join
const str = arr.join(",")
