What is JSON and why would I use it?

Question

I\'ve looked on wikipedia and Googled it and read the official documentation, but I still haven\'t got to the point where I really understand what JSON is, and why I\'d use

Answer 1

In short, it is a scripting notation for passing data about. In some ways an alternative to XML, natively supporting basic data types, arrays and associative arrays (name-value pairs, called Objects because that is what they represent).

The syntax is that used in JavaScript and JSON itself stands for "JavaScript Object Notation". However it has become portable and is used in other languages too.
