Overview
Notebooks are excellent for exploring and terrible at hidden state. Restart and run all is the only honest test of a notebook.
In this lesson you will:
- Structure a notebook so it reads top to bottom
- Avoid out-of-order execution and stale state
- Move stable code out into importable modules
Pro Tip
Use caching and revalidation wisely to ensure your app stays fast and data remains fresh without unnecessary requests.
