JSON Curriculum
History of JSON
1999: JSON (JavaScript Object Notation) was popularized by Douglas Crockford as a lightweight data interchange format for JavaScript applications.
2000s: Gained popularity for web APIs and AJAX applications due to its simplicity, readability, and compact structure compared to XML.
2010s: Became the standard for data exchange between servers and clients, widely adopted in RESTful APIs and modern web development.
Evolution: Enhanced with support for complex data structures, arrays, nested objects, and integration with most programming languages, enabling cross-platform data communication.
Current use: Extensively used in web development, APIs, mobile apps, cloud services, and data storage, making it essential for backend and front-end developers alike.

Why Learn JSON?
JSON (JavaScript Object Notation) is a lightweight and easy-to-read format for exchanging data between servers and web applications. Learning JSON allows developers to handle API responses, configure settings, store data, and communicate between front-end and back-end systems efficiently. It is language-independent, widely supported across programming languages, and essential for modern web development, mobile apps, cloud services, and IoT applications. Mastering JSON makes it easier to work with RESTful APIs, AJAX, and modern frameworks like React, Angular, and Node.js.
Future Scope After Learning JSON
The future scope of JSON is very strong as it has become the standard format for data exchange in modern web and mobile applications. By mastering JSON, developers can efficiently handle API responses, work with RESTful services, integrate front-end and back-end systems, and manage data in cloud applications. Careers include Web Developer, Back-End Developer, Full-Stack Developer, API Developer, and Data Engineer. JSON’s simplicity, compatibility with most programming languages, and widespread adoption in web, mobile, and cloud technologies make it an essential skill for students and professionals pursuing careers in software development and data-driven applications.
