Advanced React (Scrimba)

Scrimba's interactive format was perfect for learning advanced React concepts. Being able to pause, edit code, and see results immediately made complex patterns click.

The custom hooks section was the most valuable. I learned to extract stateful logic into reusable functions instead of duplicating useEffect chains across components. Building a useLocalStorage hook was the "aha" moment.

The state management module showed me when to use Context versus Redux versus local state. That decision-making framework saved me from over-engineering projects.
