Build Rust with Emscripten support

For more up2date information: http://www.hellorust.com/emscripten/

Emscripten is the LLVM-based project to compile stuff into JavaScript. Luckily, Rust already uses LLVM and just recently got an upgrade to the used version of LLVM. Now emscripten uses a fork of LLVM, which is on the way to use more or less the same base LLVM as Rust. See the next-merge branch.

This article has been given a more permanent home on my blog. Also, since it was first written, the development of the Promises/A+ specification has made the original emphasis on Promises/A seem somewhat outdated.

You're Missing the Point of Promises

Promises are a software abstraction that makes working with asynchronous operations much more pleasant. In the most basic definition, your code will move from continuation-passing style:

getTweetsFor("domenic", function (err, results) {
 // the rest of your code goes here.
