What is the purpose of using the G_scratchpad object in ServiceNow?

The G_scratchpad object serves as a mechanism to facilitate the transfer of data specifically from server-side Business Rules to client-side scripts in ServiceNow. When server-side Business Rules execute, they can populate the properties of the G_scratchpad object, making it accessible to client-side scripts that run in the user's browser context. This is particularly useful during form submissions or when displaying UI elements that rely on data computed or determined by server-side logic.

Using G_scratchpad allows developers to efficiently share data without having to perform additional server calls or complex client-side logic to retrieve the needed information. It enhances the performance of applications by minimizing unnecessary round trips to the server, thus streamlining the user experience. This design decision supports the modular nature of ServiceNow development and encourages the use of best practices by providing a structured way to manage data flow between server and client sides.
