Class Component → Uses ES6 class syntax. State is managed using this.state and updated with this.setState(). Uses lifecycle methods (componentDidMount, componentDidUpdate, componentWillUnmount). Functional Component → Just a plain JavaScript function. State is managed using React Hooks (useState, useReducer). Uses useEffect hook for all lifecycle behaviors.
