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()); }

let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(''+num); }
Template string
let num = 500; let nums = []; for(let i = 0; i < 100; ++i) { nums.push(`${num}`); }
