Custom Hooks in React Explained (in 12 mins) + Build useFetch From a Real Problem 🪝
Most tutorials explain custom hooks with definitions first.
This video does it backwards — we hit the actual problem
first, the same one you've probably run into, then build
the fix together.
What we cover:
The exact problem custom hooks solve (shown with real code)
The two rules every custom hook follows
Building useFetch from scratch, line by line
Reusing the same hook across two different components
By the end you won't just know how to use a custom hook —
you'll understand why it exists.
This sets up our next video too — we'll use this exact
thinking to build a useLocalStorage hook for a Notes app.
