can a fps controller asset be done in javascript in any other way than tut. way?

Everyone knows about the fps character controller at http://unity3d.com/support/old-resources/tutorials/fpstutorial. I am wondering is this the only code to accomplish the same function of this asset with javascript?

Btw, I barely know anything about coding, so that is why I am asking this silly question.

There’s really no reason it couldn’t be.

allright, thanks
