TOOLS YOU CAN USE

Most Real Programmers treat JavaScript like the poor cousin from the country - useful in certain situations, but not very important. Real Programmers aren't interested in a language whose primary application seems to be swapping one image with another, or drawing mouse trails across a Web page. Real Programmers have better things to do.

Well, I've got news for all your Real Programmers out there - JavaScript may be a small, not-very-exciting programming language limited to the client side of a Web transaction, but that's not a reason to count it out. Sure, it may not have the features and functions of PHP or Perl, but it sill comes with some very powerful tools - tools that can come in handy when you're trying to make your application more efficient by transferring computational load from the server to the client.

In order to illustrate what I mean, I'm going to be taking an in-depth look at one of the more powerful modules in JavaScript: its string library. I'm going to introduce you to the wonders of string concatenation, string comparison, string search and replace operations, and string formatting...all without writing a single line of Perl code.

In addition to providing a gentle introduction to JavaScript programming in general, this article will give you a broad overview of JavaScript's string manipulation capabilities, serving as both a handy reference and a tool to help you write more efficient code. Regardless of whether you're an Apprentice or a Real Programmer, you should find something interesting in here.
