One of those principles could be rephrased as: Why use XML when (X)HTML will do?
Perhaps another could be rephrased: Why bother with parsing/transforming when you can just get the data in a presentable format? After all, we all know that less code is better.
AHAH (Asychronous HTML and HTTP) is the result of applying both of those principles to the incredibly Web 2.0 buzzworthy AJAX. Strictly speaking, AHAH is simply a subset of AJAX, albeit a subset that openly de-emphasizes the X in AJAX.
AJAX Magazine provided a good overview of the advantages of AHAH over “traditional” XML-based AJAX.
So if you’ve been wondering what this AJAX stuff is about, take a look at AHAH, you might find it gets you 90% of the hyped user interface advantages with only about 10% of the hype (and effort for that matter). That’s the kind of 90/10 rule we like around here.
But don’t take our word for it. See what others have been saying about AJAX and AHAH.
