What are the best practices for using React Fast Refresh?

React Fast Refresh is a great tool for improving development speed. Here are some best practices: 1. Keep your components pure. 2. Avoid side effects in your render methods. 3. Use functional components and hooks where possible.

Can you explain why keeping components pure is important?

Keeping components pure ensures that they only depend on their props and state. This allows Fast Refresh to accurately determine what needs to be updated without unintended side effects.

What are some common pitfalls to avoid with Fast Refresh?

Common pitfalls include using class components with stateful logic, which can lead to unexpected behavior during refresh, and not properly handling module exports.

How does Fast Refresh compare to hot module replacement?

Fast Refresh is built on top of hot module replacement but focuses on maintaining component state and providing a better developer experience by ensuring that updates are reflected instantly without losing state.
