I know what JSON is and what the advantages over XML. I already read some answer for this , but still i can't get through it.

So i would specifically ask this questions:
1. Is it only useful for API thing? so exchange data without refresh the whole page using AJAX..
2. Is it always used with AJAX?
3. Do people (always/very often) using JSON like this? :: Database/Server - JSON - Client.. what i mean by that is, all our data from database will be put into JSON, so people can use it easily to any other platform/language?

**because from my point of view, if the data, which we need to output not much, why not just directly write on HTML directly, and if it's a lot of data, why not use database? If you don't mind please add an example case to use json

big thanks everyone!

    the JSON in my opinion, when you get some data from netWork , you can use the JSON to describe your data . JSON only is a data format. it isn't always used with AJAX . it's only a format. It contains array and dictionary.
