While following through the Unity3D tutorials on their website (http://unity3d.com/learn/tutorials/projects/roll-a-ball/moving-the-player) I have come across "generic functions".
http://docs.unity3d.com/Manual/GenericFunctions.html
In C++ speak, I would have called them templates. In their UnityScript it looks like this:
var obj = GetComponent.<Rigidbody>();
I've tried looking elsewhere online to get a rundown of exactly how this stuff works, and how I can write UnityScript code that uses it, but I've come up empty. I wonder if I'm just not searching for the correct terms. They say that UnityScript is based off of Javascript, but I suspect that this is specific to Unity's UnityScript compiler.
"Generic functions" do not exist in the ECMAScript version of JavaScript, only in Unity's version.
Edit: This question was posted when Unity was still calling their proprietary scripting language "Javascript", although they now seem to be calling it UnityScript again. This would have prevented the question from ever being asked in the first place.
