Welcome to Day 10 of the ServiceNow Scripting Series.

In this lesson, you’ll learn JavaScript Arrays and the most commonly used Array Methods required for ServiceNow scripting. We’ll cover creating arrays, accessing elements, updating values, array length, push(), pop(), shift(), unshift(), splice(), slice(), concat(), indexOf(), includes(), join(), reverse(), sort(), forEach(), map(), filter(), find(), reduce(), and practical examples.

Arrays are extensively used in Client Scripts, Business Rules, Script Includes, GlideRecord queries, Flow Designer, Service Catalog, and other real-world ServiceNow development scenarios.

Whether you’re preparing for the ServiceNow CSA or CAD certification or becoming a ServiceNow Developer, this lesson will strengthen your JavaScript foundation for writing efficient ServiceNow scripts.
