WebOne way to generate a GUID in JavaScript is to use the crypto module, which is built into modern web browsers and Node.js. The crypto.getRandomValues() method generates a cryptographically-secure, random array of values that can be used to create a GUID. Here is an example of how to use the crypto module to generate a GUID: WebSipHash is a cryptographically secure PRF – a keyed hash function – that performs very well for short inputs, hence the name. It was designed by cryptographers Daniel J. Bernstein and Jean-Philippe Aumasson. It is intended as a replacement for some uses of: jhash, md5_transform, sha1_transform , and so forth.
