What are the types of parameters that web blocks possess?

Web blocks in OutSystems primarily utilize input and output parameters to facilitate data handling and interaction within the interface. Input parameters allow data to be passed into the web block from the parent element, enabling the web block to use that data for rendering or processing. Output parameters are used to send data back from the web block to its parent, which can be particularly useful for returning values, triggering events, or updating parent containers based on interactions within the web block.

This design ensures that data flows effectively between components, making it easier to manage and maintain applications. While the other options feature terms like "local" and "global," which may relate to broader concepts in programming or data management, the focus on input and output parameters correctly identifies the fundamental way web blocks handle parameters in OutSystems. The use of these two types of parameters contributes to creating modular and reusable components in web applications.
