FAQ
Which UUID version does this generate?
Version 4 (random). It uses crypto.randomUUID when available and falls back to crypto.getRandomValues.
Are the UUIDs cryptographically random?
Yes — they are backed by the browser's cryptographic random number generator, not Math.random.
Is a UUID the same as a GUID?
Yes. GUID is Microsoft's name for the same 128-bit identifier standard.
