Hey @ravichandra1998g in my previous PR's i gave generic js codes non-helpful for servicenow devs so i took time and thought what is really important as in this AI/ML era i think devs might need some helpful snippets related to AI/ML
Basic use case is ServiceNow developers often need to export data to external systems. This snippet shows the production-ready pattern for:
Exporting large datasets without manual work
Creating automated data pipelines
Integrating with third-party tools
ex A company gets 10,000 incidents/month. Using this snippet, they can:

• Export historical incidents to ML system
• Train a model to predict "which incidents take longest?"
• Feed predictions back into ServiceNow
• Auto-assign complex tickets to senior technicians
