"compiled" js - what's the current state of this?

I'm taking another look at 433mhz RF - do I still need fake parameters at the front to make it work, or has that been sorted out now?

No, it works much better now. It even works with bind, which is pretty handy for even more speed.

I actually added some code up yesterday for a workshop I did: http://www.espruino.com/433Mhz

The module itself doesn't work well for receive as-is because the Web IDE doesn't compile code, but if you take the module code for rx and put it in the Web IDE, then uncomment "compiled", it works pretty well.

The only gotcha (and there's no way to really test this at the moment short of running EspruinoCompiler yourself and checking the output) is that when Espruino has to deal with floats or variables it doesn't know the type of it's much slower, so you need to get it to work with ints whenever possible.
