Shape the data first
Definition and example
Shape the data first is the focus of this lesson. Model the data as an array of objects before writing any HTML. The task asks you to apply that idea in a small example: What should you design before rendering. 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.
