Javascript work with windows 8 phone?

I apologize for asking such a simple question, but the sources ive looked through have been contradicting. Some say one can develop on the windows phone 8 in javascript, while others say that you can't. I want to know for sure if i can, as the project im working on currently has javascript within it.

 

I could not get Javascript to compile for the device, though it played fine in the editor. Then I converted every script to C# and had no compile issues and could get it to play on the device. So for me, the answer is NO, JS did not work in Unity 4.2. Not sure about 4.3.

Edit: Went back to JS on several scripts, to see if it would compile. Yes it did compile and run error free on the win phone with some JS scripts, but not others. It is a hit or miss, trial and error excercise.
