JavaScript 101 - Part 2

Summary and Further Reading

In this, the second part of our series, we played with a few more subtle features of JavaScript: arrays, the Document Object Model (DOM), and event handlers. For each of these, we began by learning what it was, then played with a practical application of the concept.

By now you should be starting to have an appreciation of what JavaScript is capable of, even if we haven't had time to describe every object in the DOM, or every event handler supported by current browsers. Grasping these concepts is really the toughest part of learning a new language like JavaScript. The rest is just a matter of getting a hold of a good reference.

Next Time

In Part 3, we'll have a close look at using JavaScript in combination with HTML forms. Among other things, we'll look at how we can validate information that a user has entered into a form before sending that data to the Web server.
