About JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is based on a subset of JavaScript language and is language-independent.

JSON is built on two structures:

A collection of name/value pairs (object)
An ordered list of values (array)

JSON is commonly used for transmitting data in web applications, configuration files, and as a data storage format. It has largely replaced XML in many contexts due to its simplicity and lightweight nature.
