What is the difference between controlled and uncontrolled components in React?

What is the difference between controlled and uncontrolled components in React?

In React, controlled components are those whose value is controlled by React state, while uncontrolled components manage their own state.

Can you give me an example of a controlled component?

Sure! A controlled component example is an input field where the value is set by the state and updated via an onChange event.

What about uncontrolled components? How do they work?

Uncontrolled components use refs to access their current value, allowing them to manage their own state without React controlling it.

When should I use controlled components over uncontrolled ones?

Use controlled components when you need to manage form data and validation in React, and uncontrolled when you want simpler integration.
