UUID v4 generator

What is UUID v4 generator

A UUID (Universally Unique Identifier) version 4 generator is a tool or function that creates a 128-bit number in a specific format that is unique across time and space. Version 4 UUIDs are generated using random or pseudo-random numbers. They are designed to have a high likelihood of uniqueness, though not guaranteed, making them suitable for use cases where a unique identifier is required. Version 4 UUIDs have the form "xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx", where each x is replaced by a hexadecimal digit and y is replaced by one of 8, 9, A, or B, indicating the UUID version and variant.
