Benchmark: json stringify vs array join dumb test

Script Preparation code:

function moreData(arr, left) {
  if(left === 0) return arr;
  else {
    arr.push(Math.floor(Math.random() * 256));
  	return moreData(arr, left - 1);
  }
}
function makeTestData() { return moreData([], 4); }

Tests:

join
let asd = "asdasd qwe d";
JSON.stringify
let asd = JSON.stringify("asdasd qwe d");
simple string concat
let asd = "asdasd qwe d" + "zxc" + "qwe";
