Which of the following is true about Client Actions in OutSystems?

Client Actions in OutSystems are specifically designed to enhance the interactivity of applications by executing code on the user's device (client side). This allows developers to respond to user interactions, such as clicks or input changes, in real time. For instance, when a button is pressed in the UI, a Client Action can be triggered to perform tasks such as manipulating visual elements, validating input, or making asynchronous calls to retrieve data without needing to refresh the page.

The nature of Client Actions means they do not directly interact with the database, which instead occurs on the server side through Server Actions. They also do not execute on the server; instead, they operate in the user's browser. Although Client Actions can process data, they are not restricted from returning data; on the contrary, they can return values or update the UI based on the actions performed. Thus, the ability of Client Actions to be triggered by user interactions is a fundamental characteristic that supports creating dynamic and responsive web applications in OutSystems.
