How do I use conditional rendering in JSX?

You can use conditional rendering in JSX by using JavaScript expressions like if statements or ternary operators.

Can you show me an example of using a ternary operator?

Sure! Here's a simple example: const element = isLoggedIn ? <LogoutButton /> : <LoginButton />; This will render either a logout or login button based on the isLoggedIn variable.

What about using && for conditional rendering?

You can use the && operator to render something only if a condition is true. For example: {isLoggedIn && <UserProfile />} will render the UserProfile component only if isLoggedIn is true.

Are there any performance considerations I should be aware of?

Yes, excessive conditional rendering can lead to performance issues. It's best to keep your conditions simple and avoid deep nesting.
