Benchmark: JSON.stringify vs template-literals vs array tostring

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:

toString
makeTestData().toString()
JSON.stringify
JSON.stringify(makeTestData());
template-literals
(`${makeTestData()}`);
