Overview of this book

Industry giants like RedHat and NetApp have adopted ServiceNow for their operational needs, and it is evolving as the number one platform choice for IT Service management. ServiceNow provides their clients with an add-on when it comes to baseline instances, where scripting can be used to customize and improve the performance of instances. It also provides inbuilt JavaScript API for scripting and improving your JavaScript instance. This book will initially cover the basics of ServiceNow scripting and the appropriate time to script in a ServiceNow environment. Then, we dig deeper into client-side and server-side scripting using JavaScipt API. We will also cover advance concepts like on-demand functions, script actions, and best practices. Mastering ServiceNow Scripting acts as an end-to-end guide for writing, testing, and debugging scripts of ServiceNow. We cover update sets for moving customizations between ServiceNow instances, jelly scripts for making custom pages, and best practices for all types of script in ServiceNow. By the end of this book, you will have hands-on experience in scripting ServiceNow using inbuilt JavaScript API.

During this chapter, we looked at basic uses of client-side scripting in client scripts and UI policies. We explored the four different types of client script and saw how each script type works. We also discovered how and when to write client-side scripts and how to test and debug them. Finally, we looked at some practical examples of client-side scripts and where uses of the different types of client script can be utilized.

In the next chapter, we continue with client-side scripting, looking at the more advanced techniques and areas where client-side scripts can be used. We take a look at script actions, AJAX calls for calling server-side scripts, and using UI actions to run client-side scripts.
