Iterate over charcters
  for (const ch of test) {
    if (!BASE36_ALPHABET.includes(ch)) {
      return false;
    }
  }
  return true;
ready
Use set+array functions
  const allowedCharSet = new Set(BASE36_ALPHABET);
  return Array.from(test).every(c => allowedCharSet.has(c));
ready
Use set functions
  const allowedCharSet = new Set(BASE36_ALPHABET);
  return (new Set(test)).isSubsetOf(allowedCharSet);
ready
Usa arrays
return Array.from(test).every(c=> BASE36_ALPHABET.includes(c));
ready
Use regex
const t = new RegExp(`^[${BASE36_ALPHABET}]+$`)
