What are the best practices for using useState in React?

When using useState, it's important to initialize state properly, avoid unnecessary re-renders, and use functional updates when the new state depends on the previous state.

Can you explain what functional updates are?

Functional updates allow you to pass a function to setState that receives the previous state as an argument, ensuring you always work with the latest state.

Are there any performance considerations I should keep in mind?

Yes, try to minimize the number of state updates and group related state variables to reduce re-renders and improve performance.

What about using useState with complex objects?

When using useState with complex objects, consider using the spread operator to update only the necessary properties, which helps maintain immutability.
