🔍⭐What is a REST API and what is it used for?

A REST API is a structure that allows different systems to communicate with each other. It's especially used so the frontend and backend can exchange data.

REST stands for "Representational State Transfer" and works over the HTTP protocol. An API is like a communication gateway that lets an application talk to the outside world.

✅For example, when a user wants to view a list of products through the app interface, the frontend sends this request to the backend via a REST API. The backend receives the request, processes it, fetches the data from the database, and sends it back to the frontend.

Thanks to REST APIs, systems can work independently from each other. This makes the software easier to scale and manage.

Understanding REST is important because it’s the foundation of most web and mobile applications today. Even though I’m just starting, I realize how useful and powerful this concept is.
