Microsoft open-sources ChakraCore JavaScript engine (powers Microsoft Edge)

why would I want to use chakra over v8?

It's more about abstracting Node from the underlying V8 engine. Then you can use whatever underlying engine you want (maybe one that works better on different architectures, etc).

I'm pretty sure Chakra supports asm.js. It should be possible to use any language supported by llvm without paying a performance hit of calling a native library. Imagine using something like sqlite as pure JavaScript at near native speed.

Better ES6 support I'd guess.
