JSON, which stands for JavaScript Object Notation, is a lightweight, text-based data interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is often used for structuring and transmitting data between a server and a web application, as well as between different parts of an application.
JSON is built on two structures:
Objects: These are unordered collections of key-value pairs. Each key is a string, and values can be strings, numbers, booleans, objects, arrays, or null. Objects in JSON are enclosed in curly braces {}
.
Arrays: These are ordered lists of values. Arrays in JSON are enclosed in square brackets []
.
It’s simplicity, combined with its human-readable format, makes it an excellent choice for data exchange and configuration. It is widely used in various applications and scenarios.
JSON’s popularity and versatility have made it a standard data format in the software development industry, facilitating data exchange and interoperability between different systems and platforms.
