How does node-uuid.v4 work?

node-uuid.v4 is a function provided by the node-uuid library that generates a version 4 UUID. A version 4 UUID is a 128-bit identifier that is generated using random or pseudo-random numbers. The node-uuid.v4 function generates 122 random bits using a high-quality random number generator, and sets the two most significant bits of the first octet to 0 and 1, respectively, to indicate that this is a version 4 UUID. The resulting UUID is a string representation of the 128-bit identifier in hexadecimal format, separated by hyphens into five groups with 8, 4, 4, 4, and 12 hexadecimal digits, respectively. This format is compatible with the UUID standard defined by RFC 4122, which specifies how UUIDs should be represented and used in software systems.

const uuid = require("node-uuid");

const id = uuid.v4();

console.log(id);

In this example, we use the node-uuid library to generate a version 4 UUID using the uuid.v4() function. The resulting id variable is a string that represents a unique identifier based on pseudo-random numbers. The format of the UUID will look something like this: Copy code
