PeepCode
Javascript with Prototype.js
Preview
by Geoffrey Grosenbach. Technical consulting by Prototype Core Team Member Justin Palmer.
Did your first few years of Javascript programming consist of “copy” and “paste”? It’s time to learn it right!
Javascript is a highly dynamic language with many interesting features which most developers never learn. Yet familiarity with Javascript is a must if you want to develop current web applications with the full power of modern browsers.
The Prototype.js library makes Javascript nearly painless. It extends native objects with extra functionality and makes it easy to organize your code or even extend built-in objects.
This 90 minute screencast shows you the basics of Javascript and walks through a few simple projects. You’ll learn about
- code organization
- writing classes
- extending objects
- attaching behaviors to elements
- simple debugging
Part II will be available next month and will cover Ajax in depth.
Source code included.

This screencast assumes familiarity with basic programming concepts like variables, loops, functions, and objects. It will show you how those work in Javascript and how prototype.js makes it easier than Javascript alone.

What People Are Saying
“Good work as always. I didn't realize how awesome Prototype was.” Jay Contonio, developer
“I watched some of the Prototype PeepCode last night and I have to say that this one has been the most informative PeepCode, at least for me. I'm learning a ton!” Richard Luther, developer
“This [Javascript with Prototype.js] video is worth watching! I highly recommend it to beginners and intermediate Prototypers, plus: Even if English is not your native language (like in my case) the speaker talks slow and understandable which makes it easy to follow. Good recording and audio quality. Thumbs up!” Kjell Bublitz, in blog comment
“The content itself is very well explained and goes into great detail covering a huge area of the subject. Javascript has always been the part of web development that I disliked. Prototype helped hugely to make it easy to work with, but this screencast has really made me look at javascript in a new light and give up the 'cut' and 'paste' style of old.” Stephen Bartholomew
“Your screencasts are absolutely wonderful! Thank you so much for making such a quality product and making it so affordable!” Matthew Erker, developer
“I make all the web developers I know and work with watch your Javascript with Prototype screencast. It's slowly helping to heal a generation of developers who directly associate Javascript with pain and suffering. I liked Javascript after I started using Prototype about a year ago. I *love* Javascript after watching your screencast.” remi Taylor, Developer

“The PeepCode Git screencast saved my sanity!” Jim Weirich, Ruby pioneer and creator of Rake
