Is there a Javascript implementation of the CryptoNight algorithm?

Question

Before I seek to write one of my own, I wanted to see if there's a CryptoNight Javascript algorithm anywhere out there. I found the CryptoNoter project, but it only contains an obfuscated binary file taht does the heavy lifting, which is banned from most browsers anyway -- https://github.com/cryptonoter/CryptoNoter/issues/34 . It would be nice if there were a JS implementation so that I could see the algorithm in action and play around with it on my local machine.

Answer 1

Sure there is.

Do a npm search cryptonight-hashing and take a pick :)

Answer 2

Yeah of course there is! As Cryptonight only uses CPU power and JavaScript is client side there are some:
