design3 also has a bunch of tutorials on javascript for Unity. I've found Unity's documentation on scripting to be extremely helpful as well.

If you're already familiar with basic programming (i.e., variables, arrays, functions, OOP, etc.), I found the FPS tutorial in the resources section of the Unity3D site to be extremely helpful for getting used to Unity's way of doing things. If not, it will probably be a little more difficult to learn basic programming concepts while also learning to use Unity. I'd suggest reading a few basic Javascript/C# tutorials first before trying to jump into Unity scripting (even if they're geared towards web development).

There is one book that I am aware of, Unity Game Development Essentials, from author Will Goldstone. This book deals with Unity Editor and Unity Api and takes you through completing a game with Unity. Every script in the book is in Unity Java Script.

Head First into Unity with JavaScript is an article in Wiki unifycommunity.com that talks about differences between JavaScript and Unity JavaScript. Digging in the Wiki you can also find sparse (but great) info about Unity JavaScript.

I found some nice explanations on object oriented programming in a book called Object-Oriented JavaScript: Create scalable, reusable high-quality JavaScript applications and libraries.

You can also consider seeing and buying some Unity video tutorials, there are some that deal with scripting, from unitytutorials.com.

The info exists but is not in one place. I find the documentation and really good. It just needs time. Perhaps when Noesis tutorials show up, we will have something a little bit more consistent.

You can consider learning Unity as a journey. As Cavafy said, "And if you find her poor, Ithaka won't have fooled you. Wise as you will have become, so full of experience, you'll have understood by then what these Ithakas mean"
