JSON stands for JavaScript Object Notation. It is a lightweight and text-based format for data interchange, designed to be easy to read and write for humans and easy to parse and generate for machines. It is often used for transmitting data between a server and a web application, as well as between different systems and platforms. JSON consists of key-value pairs, with data separated by commas and enclosed in curly braces {}. It is supported by most programming languages and is often used as an alternative to XML.
