What is the primary use of the 'g_form' object in ServiceNow?

The 'g_form' object is essential in ServiceNow for controlling form fields and values on the client-side. This object allows developers to access and manage the various components of forms dynamically. For example, developers can use 'g_form' to change field values, enable or disable fields, or make fields mandatory based on certain conditions. These capabilities are vital for creating responsive and user-friendly forms that interact intuitively with the user.

Utilizing 'g_form' enhances the user experience by providing real-time feedback and customization based on user input, which is a crucial aspect of ServiceNow's front-end functionality. This client-side manipulation is distinct from server-side operations, which are handled by different objects and functions in ServiceNow.

The other options—such as fetching user information, manipulating the server database, and defining UI Policies—represent functionalities that are either managed through different objects or are different processes in the ServiceNow ecosystem. However, they do not encapsulate the specific role of the 'g_form' object, which is primarily focused on client-side form interactions.
