Web Programming Patterns Today

From the end-user’s point of view, it makes things more feature packed; and from the programmer’s point of view, it’s a little bit more of a pain to work with than just back-end programming, especially if you’re new. Ajax by itself isn’t completely new; it’s the use of the combination of 3 different aspects of programming aspects. It’s the concept and the way we’re currently using it and where it’s headed that makes it so different and advanced. So with all this talk about Ajax, let’s go ahead and define what it is and what the benefits of its use are.

What is Ajax?

Ajax stands for “Asynchronous JavaScript and XML”. The asynchronous part is probably the most important here. It means that users get access to data from the database without having to wait for a whole new page to load with it. Data is retrieved as a user interacts with the website almost instantly and presented to the user with much less hassle. What Ajax does is combine the front-end functionality of JavaScript, and mixes it with the power of a back-end programming language such as PHP to make good web applications, rather than just simple web-pages.

What are its benefits? Some problems?

Since Ajax is not tethered to any one particular programming language, it can be used with ASP.Net or PHP all the same. The only part here that is really important is the JavaScript and XML front-end. The backend programming language can be practically anything that the server is setup for.Some of the problems associated with Ajax include the lack of support in some of the older browsers and OS’s. It can also be a bit of a pain to get JavaScript/XML/and your backend programming languages to all play together nicely.

Why do we need Ajax?

The internet has gone through many changes since just the early 2000’s. We’ve gone from a simple html pages to a pages that incorporate html/css/php/JavaScript, and a whole other latitude of aspects to bring together a much richer, much more content filled experience to the users. Ajax serves the purpose of facilitating the richness of content and the interaction of the content with users. As the internet has grown, it has increasingly become less about the code, and more about the content and so to adapt to this, concepts like Ajax are becoming commonplace for programmers.

What are some examples?

Some of the more popular examples are the live stream of data on Facebook that displays all the user information on the main user pages, as well as the way updates are shown to the user if someone interacts with their profile. Ever wonder how Google can pops-up with suggestions as you’re typing in the search box? Yep, that’s a feature courtesy of Ajax too.
