Attend Scripting in ServiceNow Fundamentals to learn how to use the ServiceNow JavaScript API. Take advantage of the extensibility of ServiceNow by adding new functionality or modifying the baseline behavior of an instance. This class begins with client-side scripting and transitions to server-side scripting. Attendees write, test and debug scripts using real-world, relevant lab exercises. The class features lecture and discussion as well as extensive hands-on practice and reinforcement of the lectures, delivered in a wide variety of lab activities.
During this interactive training course, attendees perform scripting functions in their own class instance. This provides an opportunity to practice and become comfortable with both client-side and server-side scripting.
