Run and read a JavaScript Code node

Edit Fields nodes work well for simple transformations, but sometimes you need more power — loops, calculations, or adding computed fields. That's where Code nodes come in. In this exercise, you won't write any code. Instead, you'll run a provided JavaScript Code node and study how it transforms data by comparing its input and output.

You'll import a workflow with a Code node that flattens nested weather data, execute it, and analyze the Input vs. Output panels to understand exactly what the code does.
