REST API & JSON Explained: The Foundation of the Modern Web

Every time you refresh your feed, a "Digital Restaurant" kicks into gear. 🍽️ But how do the diner (Client) and the kitchen (Server) communicate without causing total chaos?

Welcome back to StudySimply. In today’s masterclass, we’re demystifying the REST API and the JSON language. We’ll explain the "Stateless" rule that makes the internet scalable, the 4 core commands that run every website, and how JSON structures complex data using Objects, Arrays, and Nesting.

📖 On the menu today:

The Client-Server Model: Why the diner and the kitchen must stay separate.

What is REST? The architectural "operating manual" of the web.

The 4 Core Commands: GET, POST, PUT, and DELETE explained.

The Stateless Rule: Why the Chef has "no memory" of your table.

Decoding JSON: A guide to Objects, Arrays, and Nested data.
