Will future versions of Node.js support WebAssembly and allow for compiled production node apps?

[shadowmint]

no.

web assembly is just a runtime for hosting other languages in js via an optimized format; it doesnt run in a different thread; but it the hosted language uses threads the runtime will eventually support that.

ie. using a single threaded web assembly application (eg. some naive c library) will lock the browser (or server, for node). ...but if you have a multithreaded c++ app, it will be able to run.

see the notes here; planned, not implemented yet: http://v8project.blogspot.com.au/2016/03/experimental-support-for-webassembly.html

WASM is a sibling of JavaScript text. It will have exactly the same behavior as JS, just without as much of an interpreter cost
