What is the primary purpose of client variables in OutSystems?

Client variables in OutSystems serve to persist data across user sessions. They allow developers to store information that is specific to a user’s interaction with the application, enabling continuity and personalized experiences without requiring a server round trip. This means that as users navigate through different pages or screens within the application, the data saved in client variables remains accessible and can be reused, enhancing the user experience.

Using client variables is particularly effective in scenarios where data needs to be remembered during a session, such as user preferences or temporary selections, allowing for a seamless interaction with the application. This approach minimizes the need to fetch the same information from the server repeatedly, thus optimizing performance and improving response times for the end user.

In contrast, other choices do not align with the primary purpose of client variables. For example, while storing sensitive information is important, client variables are not necessarily designed for that due to security concerns. Enhancing server performance primarily involves optimizing server-side logic, whereas client variables operate on the client side. Finally, facilitating data validation is more linked to user input processes rather than the main function of client variables.
