Clean up a script
Definition and example
Clean up a script is the focus of this lesson. Split long scripts into functions, handle errors, and name things clearly. The task asks you to apply that idea in a small example: Why split a script into functions. Before you run the code, predict what should happen. Then Inspect the result produced by the exercise and compare it with your prediction. If the result differs, change one relevant line and run it again. Testing one change at a time makes the cause of a result easier to understand.
