Benchmark: string split by length: substring vs match

Script Preparation code:

function splitStr(str) {
  let i = 0; const arr = [];
  for(i = 0; i < str.length; i+=900) {
      arr.push(str.substring(i, i+900));
  }
  return arr;
}

function splitStrByExp(str) {
  return str.match(/(.{1,900})/g) || [];
}
