What is Redux Toolkit?

🤔 When I first heard the word Redux, I thought it was another library for storing data.

After building a few React projects, I realised Redux Toolkit is not just about storing data.

It is a predictable state management library.

It gives every component in the application a single source of truth so they can all access the same data without passing props through many levels.

Instead of every component managing its own copy of data, Redux Toolkit keeps one central copy.

Redux Toolkit doesn't replace Redux—it makes Redux easier, cleaner, and faster to use.

Real-World Analogy

Imagine a hospital.

Doctors, nurses, reception staff, and the pharmacy all need information about the same patient. If each department kept its own separate record, updates could easily become inconsistent.

Instead, hospitals maintain one central patient database. Everyone reads from the same source, so every department sees the latest information

             Redux Store
       ┌────────────────────┐
       │   Shared State      │
       └────────────────────┘
          ▲      ▲      ▲
          │      │      │
      Navbar   Cart   Profile

🏢 Where Is Redux Toolkit Used?

Redux Toolkit is commonly used in applications where multiple components need access to the same data.
