JavaScript is most commonly used as a client side scripting language. This means that JavaScript code is written into an HTML page. When a user requests an HTML page with JavaScript in it, the script is sent to the browser and it’s up to the browser to do something with it.

The fact that the script is in the HTML page means that your scripts can be seen and copied by whoever views your page. Nonetheless, to my mind this openness is a great advantage, because the flip side is that you can view, study and use any JavaScript you encounter on the WWW.

JavaScript can be used in other contexts than a Web browser. Netscape created server-side JavaScript as a CGI-language that can do roughly the same as Perl or ASP. There is no reason why JavaScript couldn’t be used to write real, complex programs. However, this site exclusively deals with the use of JavaScript in web browsers.

If you don’t have any programming experience at all it’s best to start with some gentle JavaScript examples that teach you the basics. It might be a good idea to buy Negrino & Smith, “JavaScript for the World Wide Web”, 4th edition, Peachpit Press, 2001. It contains some very useful examples and though it doesn’t treat advanced programming tricks, it will certainly help you get started. Of course this site also offers plenty of help.

I can also recommend Jeremy Keith, DOM Scripting: Web Design with JavaScript and the Document Object Model, 1st edition, Friends of Ed, 2005. This, too, is a book that doesn’t delve too deeply into technology, but gives non-programmers such as graphic designers/CSS wizards an excellent overview of the most common uses of JavaScript - as well as the most common problems.

Against all odds, I found myself with a little spare time this week. Rather than do something sensible like clean the garage or get some exercise, I took the opportunity to learn a new programming language: Python.

Like may SitePoint readers, I cut my teeth on PHP. I’ve become very comfortable with it over the years, warts and all. PHP continues to be a dependable choice, but PHP hasn’t changed a whole lot lately. Meanwhile, the kinds of applications I’ve been working on have been growing dramatically in both size and complexity.

Python has a lot in common with PHP: it’s a dynamically typed, open source scripting language with excellent documentation and a thriving community around it. Both languages are also a little quirky when it comes to their handling of Unicode text.

Unlike PHP, Python wasn’t originally designed as a language for Web development—it’s a general programming language that just happens to have some excellent libraries and frameworks for building web sites, like Django. This may sound like an argument against Python, but it turns out that when you start writing bigger web applications, most of your code has nothing to do with HTML, and PHP’s HTML-friendly features just seem to …
