JSON stands for JavaScript Object Notation, and it is a standard text-based format for storing and transporting data. This lightweight data interchange format is based on the object syntax from JavaScript, one of the most popular object-oriented programming (OOP) languages in use today, and essentially consists of an ordered list of pairs of names and values. Because JSON is easy for computers to parse and generate and for humans to read and write, it is an important tool for working with datasets across many different applications.
While JSON is based on JavaScript syntax, it can be used independently of JavaScript, and the simplicity of its format makes JSON’s name/value pairs readable by virtually all modern programming languages. JSON is perhaps most often used for sending and receiving data as part of web applications, often using the JSON web service protocol (JSON-WSP). It also seamlessly integrates with other JavaScript libraries such as jQuery, programming languages like Python, and web frameworks such as Django and React.‎
