Please use explicit type definitions

Do we need to create a separate state variable for range here? Can't we just calculate range from battery speed and weather state variables? Remember, when you update any state variable, it will cause your component (App.tsx) to re-render(unless you use useMemo/useCallback hooks, will get to this in a future lesson hopefully), and update all variables.

You should be using controlled inputs here, let's say we have add some function in App.tsx that runs setWeather(12), would the slider be updated to reflect the change?
