Learn Redux toolkit (RTK) which highlights the new redux best practices and the new standard of developing applications. With RTK, redux development is more efficient and easier to understand.

Redux toolkit brings the much-needed simplicity you’ve longed for in your redux development. It has out-of-the-box support to handle common use cases such as creating the redux store, creating reducers, handling immutable update logic, and much more.

At the end of the course, you will build tweetfind, a Twitter search application. This will be a great addition to your portfolio.

Intermediate Redux with Redux Toolkit

## Introduction 

To abstract the async state patterns commonly used in thunks, `createAsyncThunk` makes use of the standard `Promise` object’s state. 

Here’s a reminder. A Javascript promise can only be in one of these states:

- **Pending:** Initial state that is neither fulfilled nor rejected. 
- **Fulfilled:** The operation was completed successfully.
- **Rejected:** The operation failed.

As you may have figured out, pending could be likened to the loading state, fulfilled to the success state, and rejected could be likened to the error state.
