JavaScript can be used in which of the following components in OutSystems?

• A. Server Actions
• B. Client Actions
• C. Both Server and Client Actions
• D. Only in Screen Events

Answer: (B)

JavaScript can be utilized in Client Actions within OutSystems. Client Actions are designed to execute on the user's device and can directly interact with the browser or the mobile client. This provides the flexibility to enhance the user interface or perform operations that require real-time interaction with the user, such as manipulating the Document Object Model (DOM) or handling events like clicks and keystrokes. Integrating JavaScript in Client Actions allows developers to leverage existing JavaScript libraries and functions, thereby enriching the application with advanced functionalities and a better user experience. Since these actions run on the client-side, any JavaScript used here will execute immediately in response to user interactions, making it a powerful tool for dynamic web and mobile applications. In contrast, Server Actions run on the server-side and do not support JavaScript execution. These actions are typically responsible for data manipulation and business logic, focusing on operations that do not require user interface changes. Events related to screens, while they can also involve Client Actions, do not restrict the applicability of JavaScript to only screen events, further indicating that Client Actions are the primary place for JavaScript usage in OutSystems applications.
