What is one primary use of declaring expressions in Pega applications?

Declaring expressions in Pega applications serve a critical role in executing logic based on conditions and controlling case flow. They provide a mechanism for implementing dynamic decision-making processes within the application. This can involve evaluating conditions to determine the path a case will follow, updating properties based on specific rules, or managing case stages based on the outcomes of evaluations.

By leveraging declaring expressions, developers can ensure that the application behaves as intended, directing cases appropriately and allowing for real-time adjustments to the flow based on current data. This capability is essential in fostering a responsive and adaptable application environment that aligns with user expectations and business rules.

In this context, other options might address different functionalities, but they do not directly encompass the primary purpose of declaring expressions, which is fundamentally tied to the control and execution of logic in case flows.
