XML, long used as a method for exchanging data, is giving way to JSON, now considered the gold standard. But is JSON always the right choice over XML? As an API designer, it’s important to understand the foundations of JSON and XML, as well as the differences between them.

Well I had a slow bus ride home tonight (friday is always slow) and i took a pile of "JSON" tutorials with me. So now I can gently lead you through some BabySteps in JSON. here we go... JSON Basics: What You Need to Know. Tutorial by Matt Doyle | Level: Intermediate | Published on 24 March 2011 Categories: What is JSON, and what can it do?
However, learning to use it by reading its specification is like learning to drive a car by looking at its blueprints. You don’t need to know how an internal combustion engine fits together if all you want to do is pick up the groceries.

It’s for those that want to write it and understand it, but maybe aren’t interested in building their own car—er, writing their own JSON Schema validator—just yet.
