uuidv4 javascript

To generate a UUIDv4 in JavaScript, you can use the uuid package. Here's an example of how to do it:

const { v4: uuidv4 } = require('uuid');

const uuid = uuidv4();
console.log(uuid);

Make sure you have the uuid package installed before running this code. You can install it using npm:

npm install uuid

This code will generate a UUIDv4 and log it to the console. The generated UUID will be a string in the format xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx, where each x is a hexadecimal digit and y is a hexadecimal digit from the set [8, 9, A, or B].

Please note that the uuid package is not a built-in module in Node.js, so you need to install it separately.
