Equivalent to python's uuid.uuid4().hex in javascript?

Python has functionality to create hex UUID's like so:

>>> import uuid
>>> uuid.uuid4().hex
'47be94c37e484e13ab04ed3c54a5b681'

A solution idea is to just generate each of the 32 characters randomly on the frontend, but I don't know if there's anything special about the hex UUID's, and I'm also not sure if there's a good way to validate the client sent back a valid value (and not a series of 32 a's)

Edit: just realized there's nothing special about the "hex" formatting, it's just missing the dashes. Will leave that bullet up in case it confuses anyone else.

You can use buffer to convert to hex conveniently.

const uuid = require('uuid')
const buffer = Buffer.alloc(16);

uuid.v4({}, buffer);
console.log(buffer.toString('hex'));

Not the cleanest and most elegant solution but will get the job done.
