A Business Rule can take actions such as setting field values and generating an event without scripting. A Business Rule is a server-side script that runs when a record is displayed, inserted, updated, deleted, or queried. A Business Rule can use filter conditions, role conditions, and actions to define when and how it should run. Actions are predefined operations that can be performed on a record, such as setting field values, generating an event, adding a message, or writing to the system log. These actions do not require scripting and can be selected from a drop-down list. Reference: Use business rules and client scripts to control field values

Application developers configure ServiceNow using industry standard JavaScript to extend and add functionality. JavaScript is a scripting language that enables developers to create dynamic and interactive web pages, as well as manipulate data and logic on the server-side. ServiceNow provides various APIs and frameworks for developers to use JavaScript to customize and enhance the functionality of their applications, such as client scripts, UI policies, business rules, script includes, UI actions, and more.

The step that does not belong when creating a Utils Script Include is identifying the table. A Script Include is a server-side script that can contain one or more classes or functions that can be reused by other scripts. It does not depend on a specific table, but can access any table through GlideRecord or other APIs. The other steps are part of creating a Script Include class and its prototype object. Reference: [ServiceNow Docs - Script Includes], [ServiceNow Docs - GlideRecord API]

gs.print() and gs.log() are older and not available in scoped applications, whereas gs.debug(), gs.info(), gs.warn(), gs.error() work in both scoped applications and global are therefore are more versatile going forward in future versions.
