Full Form of JSON

What is JSON?

JavaScript Object Notation (JSON) 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 built on two universal structures: a collection of name/value pairs (object) and an ordered list of values (array). JSON is language-independent, though it uses conventions familiar to programmers of the C-family languages. In India, JSON has become an essential part of modern web and mobile application development, especially with the rise of startups and digital services. It is widely used for transmitting data between a server and a web client, such as when you book an IRCTC ticket or check your bank balance via a mobile app. JSON is also the backbone of many APIs provided by Indian government portals (like DigiLocker and UMANG) and private e-commerce platforms. It replaced XML in many contexts because of its simpler syntax and smaller payload size. For students preparing for computer science or information technology exams, understanding JSON is crucial for topics like AJAX, RESTful web services, and data structures. It appears in competitive exams like GATE, UGC NET, and campus placement tests. JSON's ubiquity in cloud computing and IoT further cements its relevance in India's growing tech landscape.
