JSON (JavaScript Object Notation) is designed on a text-based syntax and is easy to read and write. It allows the representation of data objects and their properties in the form of key-value pairs. These key-value pairs can also be organized in nested structures, allowing complex data hierarchies to be represented.

Advantages of JSON for REST and API

In the context of REST-based APIs, JSON is often used as the preferred data format because it is lightweight, platform-independent, and easily readable by both humans and machines. For example, JSON is often used for retrieving data from a server or sending data to a server.

JSON is a standard format

Thanks to its simplicity and flexibility, JSON has become a standard format for data exchange in many modern web applications. It supports various data types such as strings, numbers, booleans, arrays, and objects, and is natively supported by many programming languages and frameworks.
