Introduction to Scripting in ServiceNow

ServiceNow uses industry-standard JavaScript to extend application functionality. ServiceNow APIs (Application Programming Interfaces) provide classes and methods to do things like:

• • • Perform CRUD operation on tables: query, update, create, delete
    • Data Validation
    • Write to log files
    • Prompt users with alerts, confirmations, or messages
    • Interact with 3rd party web services
    • And more…

Note:

• • • ServiceNow has used Java as backed technology.
    • All classes has been written in Java
    • Using Javascript we call the classes via API.
    • No need to know Java in order to become successful ServiceNow Developer.
