I'm normally unimpressed by applications ported to javascript. However, this actually has me excited. I would love to be able to edit all my Dropbox text files with a web interface. If anyone here works for Dropbox, I beg you to integrate this!

http://dillinger.io/ you already can

There is also http://stackedit.io

See also http://codemirror.net/demo/vim.html (though that's only the editor component, not a whole vim implementation)

While this is impressive, I find it surprisingly slow compared to much more demanding applications with bigger code bases compiled via Emscripten. Any ideas why?

Well, I don't know what you mean by slow, but it could be the use of setTimeout() every 10ms to simulate[1] Vim's synchronous busy-wait is affecting responsiveness.

Lu mentioned[2] on vim_dev that it was necessary to write a hack for this portion.

This is pretty cool. Backspace not working for me though in Chrome.

Same here, Chrome on Debian.

Backspace and ESC not working, so after I enter a mode I'm stuck in it forever.

Earlier quoted context omitted.

if you use vimium/vimperator/something else you can do shift+H to go backwards, shift+L to go forward.

Which would require me to press two keys instead of one.

Considering we're talking about Vim here, pressing keys should be second nature to you anyway...

Rule 34 for software: If it exists, there IS a javascript port of it.

That would be Atwood's Law: any application that can be written in JavaScript, will eventually be written in JavaScript. http://www.codinghorror.com/blog/2007/07/the-principle-of-le... And tlrobinson's Law (or corollary?): Any submission to Hacker News about a novel JavaScript program will contain a comment referencing Atwood's Law. https://twitter.com/tlrobinson/status/395636386671235072

What about emacs in Linux in JavaScript? :-)

I really hope someone will patch it into the IPython notebook (or at least enable the codemirror vim keybindings). If I can find the time to learn some javascript I'll give it a go myself.
