What you'll learn

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. If you're a Rails developer, it's time to learn the magic behind the Javascript libraries that ship with Rails. You may even find yourself taking advantage of the power or Prototype instead of using the Rails helpers that insulate you from the process! If you want to use Prototype with another server-side framework, you'll learn the client-side basics you need to be confident with Ajax.
