What are controlled components in React?

Controlled components are React components that do not maintain their own state. Instead, they receive their current value and update callback via props.

Can you give me an example of a controlled component?

Sure! A simple example is an input field where the value is controlled by React state. You can use the value prop to set the input's value and an onChange handler to update the state.

What are the benefits of using controlled components?

Controlled components provide better control over form data, easier validation, and the ability to manage the state in a single place.

Are there any downsides to using controlled components?

Yes, controlled components can lead to more boilerplate code and may impact performance if not managed properly, especially in large forms.
