var arr_small = Array.from({ length: 1000 }).map((_, i) => `test_val${i}`);
var arr_big = Array.from({ length: 1000000 }).map((_, i) => `test_val${i}`);
Tests:

  • stringify

     
    JSON.stringify(arr_small);
    JSON.stringify(arr_big);

  • join

     
    arr_small.join('');
    arr_big.join('');

  • toString

     
    arr_small.toString();
    arr_big.toString();
