What is JSON?

JSON (JavaScript Object Notation) is a data format that was created to be easily readable for both humans and computers. It has become the most popular way for applications to exchange data, and its most commonly encountered when working with APIs.

The minimal syntax and simple parsing of JSON increases the speed of communication in multiple
ways.

• It often contains less data to download compared to other formats
• It can be interpreted in most modern languages without external libraries

For these reasons, along with being self-describing and easy-to-read, JSON remains the data format choice for most developers.
