Revisiting x State x Management

State being the only trigger of the update phase makes it the most important concept in the React's land. But with great power, comes great responsibility: State management.


Many libraries are out there trying to find a way to make this easier, but every time we maintain a codebase, we find even worse _state crimes_:

- Cannot update the state of unmounted components
- Showing the results of an early request
- Unnecessary re-renders
- No pending states
- Useless state variables
- Useless useEffects
- No cancellations
- No sharing
- Flashing old state
- And many more you can tell


This talk is more of a retrospection about all the crimes we've done managing state, while proposing _efficient_ alternatives for every widespread bad and anti-pattern.
