Which of the following scenarios would require the use of Client Scripts over UI Policy Actions?

Client Scripts are specifically designed to handle tasks that need to be executed on the user's browser, making them ideal for performing client-side calculations. These scripts allow developers to manipulate form fields in real time, respond to user actions, and dynamically update interfaces based on user input. In scenarios where mathematical calculations or other logic needs to be processed on the client side without requiring a round trip to the server, Client Scripts become a crucial tool.

While UI Policy Actions can also change field attributes and manage visibility based on certain conditions, they are not as flexible or powerful for executing custom logic or calculations in real time as Client Scripts are. Server-side logic, such as what is managed through Business Rules or Script Includes, cannot be performed by Client Scripts, which are limited strictly to the client-side environment. Triggering notifications typically relies on server-side features and is not a function of Client Scripts, further emphasizing the need for the right tool based on the scenario at hand.
