Why does useContext work without Context.Provider?

Question

Can you explain me why useContext() works for me if I don't wrap my components with Context.Provider? I just exported result of "createContext(someValues)" with predefined values and called useContext(exportedContext) in component and it works. Every tutorial tells me to wrap components. Has something changed in React?

Answer 1

All consumers that are descendants of a Provider will re-render whenever the Provider’s value prop changes. In other words, If you don't wrap your components with Context.Provider they won't get re-rendered when the someValues in createContext(someValues) changes. You will get the initial value that you set only in the first render.
