Tests:

  • String()

    AخA
     
    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());
    }

  • Concatenation

     
    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}`);
    }
