Data aggregation and transformation from sample input to output

• Aggregate numerical data from multiple sources.
• Transform input items by adding new fields.
• Calculate sums or other metrics from datasets.
• Demonstrate JavaScript code execution in workflows.

Initiate the workflow with a manual trigger. Generate sample data for processing. Run code to calculate the sum of values from all items. Add new fields to each item using different coding techniques.
