How can I optimize performance in my React app using Immer?

You can optimize performance in your React app by using Immer to manage immutable state updates efficiently. Immer allows you to write simpler code while ensuring that your state updates are optimized.

What are some specific techniques I can use with Immer?

Some techniques include using the produce function to create drafts of your state, leveraging set to update nested properties, and avoiding unnecessary re-renders by using selectors.

Can you give me an example of using Immer in a Redux setup?

Sure! In a Redux reducer, you can use Immer like this: const reducer = produce((draft, action) => { if (action.type === 'ADD_TODO') { draft.todos.push(action.payload); } }, initialState); This keeps your code clean and efficient.

Are there any performance drawbacks to using Immer?

While Immer is generally efficient, it can introduce overhead in very large state trees or in scenarios with frequent updates. It's important to profile your app to ensure it meets your performance needs.
