JSON stands for JavaScript Object Notation. It is the most common format used to send and receive data between a client and a server.
When you work with APIs, almost all responses come in JSON format. Learning how to read, create, and use JSON data is essential for building modern web applications.
JSON looks similar to JavaScript objects, which makes it easy for developers to understand and use.
Why JSON is Important
- It is lightweight and fast
- Easy to read and write
- Supported by all programming languages
- Used by almost every API
- Works perfectly with JavaScript
JSON is the standard language of data exchange on the web.
This data looks like a JavaScript object, but it follows JSON rules.
Keys are always written in double quotes in real JSON data.
JSON.parse() converts a JSON string into a JavaScript object.
This allows you to work with API data inside your program.
These examples show how JSON data is converted between strings and objects.
By mastering JSON handling, students gain the ability to work confidently with APIs and build real-world, data-driven JavaScript applications.
