What are lifecycle methods in React components?

class MyComponent extends React.Component {
            componentDidMount() {
                // Invoked immediately after a component is mounted
                console.log("Component mounted!");
            }

            componentDidUpdate(prevProps, prevState) {
                // Invoked immediately after updating occurs
                console.log("Component updated!");
            }

            componentWillUnmount() {
                // Invoked immediately before a component is unmounted and destroyed
                console.log("Component will unmount!");
            }

            render() {
                return <div>Hello, World!</div>;
            }
        }
