Emscripten takes in C/ C++ code, passes it through LLVM, and converts the LLVM-generated bytecode into JavaScript (specifically, Asm.js, a subset of JavaScript).
If the compiled Asm.js code is doing some rendering then it is most likely being handled by WebGL (and rendered using OpenGL). In this way the entire pipeline is technically making use of JavaScript and the browser but is almost entirely skirting the actual, normal, code execution and rendering path that JavaScript-in-a-webpage…

…Retina display. There are also a number of improvements to the LLVM compiler and Objective-C language, including some new warnings to help find subtle bugs when using ARC and weak references.
The improvement that jumped out at me is a simple one, but one that is already saving me a lot of frustration. It used to happen when typing in the class name NSString. This problem is best explained by this classic pic from the Tumblr called Texts from Xcode:

Numba is a Python compiler for NumPy and SciPy. It replaces byte-code on the stack with simple type-inferencing. It translates to LLVM. The code then gets inserted into the NumPy runtime. They use LLVM-PY. They have a @numba.compile decorator. It's from Continuum Analytics.
IHasAMoney.com is a replacement for mint.com. He doesn't trust mint.com. IHasAMoney.com does not require the use of a mouse--it's for hackers. You can run it locally so that you don't have to give another web site your bank passwords.

…separate software products, but there exists llvm-gcc which is a GCC backend that utilizes LLVM. All OS X versions <= Snow Leopard originally shipped with regular gcc, but as of Xcode 4 (which is also the default on OS X Lion) Apple has switched to llvm-gcc as their default compiler. " Hurray", some people may think, as they heard that LLVM generates better code and/or is faster than default GCC. Unfortunately, the reality is not that great.

LLVM 2.8 We've upgraded to using LLVM version 2.8, the latest released version. LLVM powers the high performance compiler Rubinius uses to compile Ruby code all the way down to machine code. This brings some minor performance improvements related to better optimizations, but this mostly paves the way for future high-level optimizations that we'll be implementing with new LLVM 2.8 features.
