There has been a fair amount of hype/discussion recently over the fairly new JSON format. JSON is a lightweight data-interchange format based on a subset of the JavaScript programming language. Since many people that read my blog do not program for a living, I will try to spare the details (let alone the fact that most programmers will know what JSON is and don’t need a repeat explanation). If you want to read a great analysis of JSON you might want to check out a great entry from Dave Winer’s blog. To be honest, I’m not quite sure that I’m even qualified to talk about comparing XML and JavaScript, so I’ll just point you in the direction of a few articles that summarize everything pretty darn well.
