I don't mean to be "that guy" and nitpick the benchmarked code, but... I'm gonna be.

The TodoMVC React code was written for an old version of React. If you actually pop it open and try using it, it throws an error (try editing an item). React.findDOMNode hasn't been a thing since React 0.13; that should be changed to ReactDOM.findDOMNode.

Hand-optimized React 15 code would also switch all the components from React.createClass to extending React.Component, which is the new hotness and (AFAIK) renders faster. This would necessitate adding another Babel transform to the React demo.

I couldn't figure out how to actually run this (locally, so I could make changes).

When I open index.html, I just get ReferenceError: Elm is not defined. That was after installing Elm and doing elm-package install in src which was just a guess on my part. That didn't seem to fix anything.

Instructions for setting this up would be nice!

Thanks for a great article! I'm very sorry for opening an issue for this, but I couldn't understand how does Elm gets around the issues you mention for requestAnimationFrame. Could you please point me in the right direction?

Any interest in a PR for scripts to run on node with C code coverage?

You would get info with just strace, but I am interested in Node code blocks and Node hints that could be optimized to give Elm performance on par with Haskell.

Hi @evancz amazing work with Elm 👍 I am really looking forward to add some Elm at work.

I found that the benchmark results differ in a considerable way when I tried it in Firefox.

Environment:

• MacBook Pro (Retina, 15-inch, Mid 2014)
• OSX El Capitan 10.11.6

Firefox 48.0.2

As you can see in the screenshot Angular 2 is the winner in both naive and optimized implementation. Also it is quite strange why there such a big performance difference in almost all implementation, they are approx. 2X slower in firefox than in chrome.
