JSONP or "JSON with the addition"

From Wikipedia:

"JSONP or" JSON with the addition "is a JSON extension in which the prefix specified as an input argument call itself. This optional prefix is ​​usually the name of a function callback, but it can also be an assignment variable, an if statement, or any other Javascript instruction prefix. it appears to have been made on a MacPython blog in 2005 [16] and is now used by many 2.0 websites, such as Dojo Toolkits, Google Toolkit Applications [17] and web services. Further extensions to this protocol have been proposed by considering additional additional input arguments such as, for example, this is the case of JSONPP [18] supported by S3DB web services. Since JSONP uses script tags, calls are essentially open to the world. For this reason, JSONP may not be practical to transfer sensitive data.

Answer 5

Actually, while the other answers are good, JSON-P does not require the use of JSON. You can use any data format you like if it follows the same idea as JSON-P. It refers more to the process of submitting a callback to the server, which will be used in JavaScript code that is returned in response.
