    AخA
     
    let nums = [];
    for(let i = 0; i < 100; ++i) {
      nums.push(String(i));
    }

  • .toString()

     
    let nums = [];
    for(let i = 0; i < 100; ++i) {
      nums.push(i.toString());
    }

  • template string

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

  • concat with string

     
    let nums = [];
    for(let i = 0; i < 100; ++i) {
      nums.push(i + "");
