const stringByteLength = (string) => {
  let byte = 0;

  for (let i = 0; i < string.length; i++) {
    const char = string.charCodeAt(i);
    if (char >> 11) {
      byte += 3;
    } else if (char >> 7) {
      byte += 2;
    } else {
      byte += 1;
    }
  }

  console.log(byte);
  return byte;
};

(c == 10 ) ? 2 : (( c >> 7 ) ? 2 : 1))
