Which of the following statements about the Lightning Components framework is true?

1. It uses JavaScript on the client side and Apex on the server side.

2. It uses events to communicate data between components.

3. It uses a stateful client and stateless server architecture.

4. All of the above.

The correct answer is: All of the above.

The statement that all of the provided options about the Lightning Components framework are true is accurate due to the following reasons: The Lightning Components framework indeed utilizes JavaScript for client-side logic, allowing for enhanced user interactions and dynamic updates without requiring full page reloads. On the server side, it leverages Apex, Salesforce's proprietary programming language, to handle business logic and data access. This combination allows developers to create responsive applications that can efficiently process data. Additionally, the framework employs a robust event-driven architecture for communication between components. Events can be fired by one component and handled by others, enabling a seamless flow of data and interactions within the application. This decoupling of components through events fosters a modular approach, allowing for easier maintenance and updates. Furthermore, the framework follows a stateful client and stateless server architecture, which means that the client maintains its state while the server does not maintain any session information. This approach leads to performance benefits and scaling advantages as the server handles requests independently without retaining state information. Given that all these aspects are true and applicable to the Lightning Components framework, it confirms that all options collectively represent accurate characteristics of the framework.
