"We're going to get down and dirty with just-in-time compilers for JavaScript, all the way down to the bare metal. We're going to present three major JavaScript JIT technologies. First, we'll crack open general-purpose JIT compilers like Firefox 4's JaegerMonkey. Next, we'll dive into inline caching, which allows JaegerMonkey to optimize property access, and more generally adapt and re-optimize as code runs. Finally, we'll show off fully optimizing compilers like our next-generation IonMonkey project, which uses type information to enable advanced optimizations. For each technology, we'll give an overview, discuss performance characteristics, and analyze generated assembly code in depth. Warning: presentation includes self-modifying code."

"Emscripten is an open source LLVM to JavaScript compiler. It lets you take code written in C or C++ and run it on the web. It can also be used to compile entire language runtimes, like CPython, letting you run code in those languages on the web as well. Currently a major focus of work in Emscripten is connecting with 'normal' JavaScript code. In other words, making it easy to compile some existing C++ library, then use it from your handwritten JavaScript on the web."
