UUID生成

ランダムな汎用一意識別子 (UUID v4) を生成します。

In software engineering and data management, having a truly unique identifier is essential to prevent data collisions and sync errors. A Universally Unique Identifier (UUID), also known as a GUID, is a 128-bit label used for information in computer systems. Because they have a massive number of possible combinations, you can generate them independently without a central authority and still be confident that no two IDs will ever be the same.
