What are controlled components in React?

Can you explain what controlled components are in React?

Sure! Controlled components are form elements whose value is controlled by React state. This means that the form data is handled by the component's state rather than the DOM.

How do I implement a controlled component in my React app?

To implement a controlled component, you need to set the value of the input to a state variable and update that state on change. Here's a simple example:

function MyComponent() {
  const [value, setValue] = useState('');

  const handleChange = (event) => {
    setValue(event.target.value);
  };

  return <input type="text" value={value} onChange={handleChange} />;
}

What are the benefits of using controlled components?

Controlled components provide better control over form data, easier validation, and the ability to manipulate the input values before submission.
