What type of unique identifier should you use for your next data-backed project? Incremental integers? UUIDs? A URL-friendly short ID? I present: the LOL ID.

'lxxxxxxxxl'
  .replace(/x/g, () => Math.random() > 0.5 ? 'l' : 'o');

%[https://codepen.io/travishorn/pen/BOwPjb]

This code generates a random ID that starts and ends with “l” and contain eight random “o”s or “l”s.

Some random LOL IDs generated with this code:

• lloollooll

• lolollloll

• lololloool

• loolololll

• loloooolol

Disclaimer

Don’t actually use this code for anything, ever. The IDs are not guaranteed to be unique by a looong shot.
