What is JSON?

JSON stands for JavaScript Object Notation and is a lightweight text-based format used to store and exchange structured data.
JSON uses a simple structure based on objects and arrays, making data easy to organize and understand.
It is human-readable, while also being easy for computers and programming languages to parse and generate.
JSON is language-independent and is supported by many programming languages, including JavaScript, PHP, Python, Java, C#, C++, Ruby, and Go.
JSON is widely used for data exchange between web browsers, servers, applications, and APIs.
JSON data is commonly used in REST APIs, web applications, mobile apps, configuration files, and database-related applications.
A JSON object stores data using key-value pairs, while arrays are used to store ordered collections of values.
JSON supports common data types such as strings, numbers, booleans, arrays, objects, and null.
Its simple syntax and broad programming-language support make JSON one of the most popular formats for structured data exchange.
JSON files normally use the .json file extension and can be created, edited, formatted, validated, and processed using various development tools.
