What is a UUID?
A UUID (Universally Unique Identifier) is a 128-bit identifier formatted asxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. UUID version 4 (v4) identifiers are generated from random or pseudo-random numbers, making collisions statistically negligible for practical purposes.
When to Use UUIDs
UUIDs are ideal for database primary keys, session tokens, request correlation IDs, and anywhere you need a unique identifier without a central authority. This generator uses the browser'scrypto.randomUUID() API for cryptographically secure random values.
