Where/when we use JSON?

Question

Could you please tell me, what is the use of JSON (in Javascript and PHP). when we need a JSON method.

I read from the following link but, i didn't get any information regarding the JSON implementation on any project.

Answer 1

JSON is a light-weight data-interchange format (think of it as XML on a diet). Basically any place where you can use XML for serializing data you can use JSON instead.

Answer 2

Despite its name, one of the primary uses of the JSON format is in AJAX web development (though certainly not the only one). It is often preferred over the traditional XML for its light-weight syntax.
