JSONP

So, as the JSONP requests for the Js file from the other server, so is it storing whatever the data is inside the Js (requested ) file in the JSON file or it's just helps to get the Js file from other server, if the second one is true then why do we need JSON for that, as it just helps to store data in a organized manner?

So JSONP is essentially doing two things, 1, it sends a query to the server, (what data is needed) 2. it tells the server what function to send the data to.

The server will then send data as a JavaScript function to the local function specified. While the server could send the data in another format (still inside a js function though), it is standard practice to use JSON. JSON is the native storage method in JavaScript and is usually going to be the best way of storing the data. JSON stands for (JavaScript Object Notation).

So, basically yes, JSON is used to make the data easier to work with.
