On the client side, what function do you load in a scoped UI Script library?

The correct answer is ScriptLoader, which is the function used on the client side for loading scoped UI script libraries within ServiceNow. This function provides a streamlined way to include JavaScript libraries that are specific to a particular scope, promoting modular development and code organization.

By utilizing ScriptLoader, developers can ensure that their client-side scripts are properly loaded into the application context, allowing them to access the specific functionality and variables defined within that scoped library. This is crucial for applications that require particular code organization and modularization, as it helps avoid naming conflicts and promotes cleaner code practices.

The other options, while they may sound plausible, do not correspond to the mechanism for loading scoped UI script libraries in ServiceNow. For instance, UIManager typically refers to managing user interface components rather than loading scripts, and ClientHandler and LoadScripts do not represent the standard methods used for this purpose in the context of ServiceNow. Thus, understanding the functionality of ScriptLoader is key for any developer working within the scoped application framework in ServiceNow.
