JSON Tutorial

JSON, or JavaScript Object Notation, is a lightweight, text-based data format used for storing and exchanging data between systems.


Prerequisites for Learning JSON

It would be very helpful if you have the following foundational knowledge:

1. Basic Programming Concepts

Understanding of variables, data types, and data structures like arrays and dictionaries (or hash maps in some languages).

2. Familiarity with JavaScript (Optional)

While JSON is derived from JavaScript, you don’t need to know JavaScript to use it. A basic understanding of JavaScript objects may help in grasping JSON quickly.

3. Knowledge of Data Interchange

Familiarity with how data is sent and received between systems, such as APIs or client-server communication.

4. A Text Editor or IDE

Tools like VS CodeSublime Text, or even a basic editor like Notepad can be used to create and edit JSON files.

While these prerequisites can be helpful, they are not mandatory. Don’t worry if you encounter concepts beyond JSON; we’ll explain everything in a simple and beginner-friendly way as we go along.
