Eight Weeks of Prototype: Week 3, Prototype Data Types

Summary

In this article we looked the different data types available in Prototype. A large number of new methods have been added to existing JavaScript data types to make most functionality very simple to code.

We looked extensively at enumerables and specifically, the Hash type. Enumerables are very useful and come up frequently when developing with Prototype (such as selecting elements from the Document Object Model with $$() or select()).

In the next article of "Eight Weeks of Prototype" we will look at how to handle events in Prototype. This includes both native browser events as well as how to make use of custom events in your development.
