About the UUID Generator
A UUID version 4 is 122 random bits formatted as 36 characters. Collisions are so improbable that independent systems can mint identifiers without coordinating.
Generation uses the Web Crypto API, so the values come from a cryptographically secure random source rather than Math.random.
