@patrickren7395 Жыл бұрын

Great video. One topic I'd appreciate you to touch on is where state is actually stored in a FC. Every state change causes the whole component function to re-run, I'm wondering why the second time the `useState` func runs, the state won't be initialized again. My guesss is the state is stored in a store managed by react & `useState` somehow `hooks` the FC with the actual state.
