Can we all please read at least a reasonable portion of the comments before repeating some form of "its insecure because its in the browser!"? Upvote one of the existing comments if you think that's important to talk about here. Yes, there are potential issues with that, and yes it would be wise to instead download the code, peruse it, and then run it locally if satisfied with its security. Now that that's over with, can we talk about some of the interesting aspects of the post?

Have others tried programming a project in one language and transcribing it to another? I work with a fair number of languages, and I find myself falling into a distinctive mindset with each one. Several of the nice idioms I use in one language don't seem like they'd translate well to another. Beyond being an interesting exercise in the mindset behind both languages, are there any benefits to this? It seems like you'd have to cut features you might normally use in the source language until you've reached a union with features from the destination language. It seems like that'd be a pretty tough transition going from a typed and functional language like Haskell to JS.
