How do I use Immer in my React project?

To use Immer, first install it via npm or yarn. Then, you can create a draft state in your reducer.

Can you show me a simple example?

Sure! Here's a basic example:

import produce from 'immer';

const initialState = { count: 0 };

const reducer = (state = initialState, action) => {
  switch (action.type) {
    case 'increment':
      return produce(state, draft => {
        draft.count += 1;
      });
    default:
      return state;
  }
};

What are the benefits of using Immer?

Immer simplifies state updates by allowing you to write mutable code while keeping the state immutable. It also helps prevent bugs.
