Method, examples and limits

Each UUID uses 16 random browser bytes with version 4 and RFC 9562 variant bits. The format is xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where y ranges from 8 to b. It contains no timestamp or hardware address. Collision probability is very low, but persistent keys should still use a database uniqueness constraint. The generator does not keep a record of used identifiers.
