What is JSON? Why, when and where to use? I am confused.

JavaScript Object Notation is a flexible syntax for defining data structures. Despite the name it is used by multiple programming languages.

Its most common use case is in system to system communications over the internet. Many REST APIs send and receive payloads in JSON. Many also support XML. XML and JSON could be said to be trying to solve similar problems.

That said, when writing JavaScript programs you will often store data in or load data from a JSON format (if you need to store or load data) as well as using JSON for communicating with Web Service APIs.
