Javascript

Last updated: 2006-12-10 00:00:00

Javascript is a Web essential - along with HTML, it is nearly impossible to create a modern, dynamic website without it. It isn't the easiest language to learn, but if you stick to simple things you'll get the hang of it and in no time you will be coding right along with the best of them. Or at least you'll get something to work, somehow.

Javascript as a first language

If you are interested in learning to program Web sites, you will want to learn HTML and Javascript: These are the fundamental building blocks of dynamic Web sites.

Javascript can be used in a number of ways, but its most common use is in client side Web programming. What does client-side mean? Well, in this case, it means that Javascript is used in Browsers to improve the user exprience.

Javascript examples are easy to find

Because Javascript is so common in web pages there are tons of examples of Javascipt code on the internet. Of course, there are numerous sites for programmers that have tutorials, sample code, game code, and endless other materials about Javascript. But there is another source for good examples: And that is the Html source of any web page that contains JavaScript. If the code is "in-line" (that is, not in an include file), you can just view the source to see the Javascript in the page. Because Javascript is an interpreted language, it is generally available for you to view.

If the file is included as a resource for the url, you can still get access to it.

Sometimes the code is obfuscated - that means that it has been altered by an automated tool to make it difficult to read... for now, just ignore any scripts that are obfuscated - there is plenty of clear code for you to view.
