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 would use the value prop to set the input's value and an onChange handler to update the state.

How do controlled components differ from uncontrolled components?

Controlled components rely on React state for their values, while uncontrolled components manage their own state internally, often using refs.

When should I use controlled components?

Use controlled components when you need to manage form data, validate input, or synchronize with other UI elements.
