JSON (JavaScript Object Notation) is a lightweight data interchange format used for transmitting and storing data. It is a text-based format that is easy to read and write by both humans and machines. JSON is often used in web applications to transfer data between servers and clients, as it is a simple and efficient way to represent structured data.
JSON syntax is based on a subset of JavaScript, but it is language-independent and can be used with most programming languages. JSON data is represented using key-value pairs, where keys are strings and values can be strings, numbers, arrays, objects, or Boolean values. JSON objects are enclosed in curly braces, and each key-value pair is separated by a comma.
JSON is similar to XML in terms of its purpose and functionality, but it is considered to be a more lightweight and flexible format. It is also easier to read and parse than XML, as it does not have complex formatting or tag structures. JSON can be used in a variety of contexts, including web APIs, data storage, and configuration files.
JSON has become a widely used format for data exchange due to its simplicity and ease of use. It is supported by most modern programming languages and web browsers, and is used extensively in web development, mobile app development, and other data-intensive applications.
