Looks like client-side JS has window.crypto.getRandomValues() for this:
https://developer.mozilla.org/en-US/docs/Web/API/RandomSource/getRandomValues
Similarly, Node.js offers crypto.randomBytes():
https://nodejs.org/api/crypto.html#crypto_crypto_randombytes_size_callback
Also, it's spelled "JavaScript", not "Javascript".
Additionally, it looks like there's some kind of bold formatting error
in the answer to "Q: What about a password generator?" in the HTML
version of the PEP.
