React JS Context API Tutorial | Learn useContext & Global State

Описание: What is Context API?
The Context API is a React feature that allows you to share data across components without passing props manually at every level (avoids prop drilling).
It is useful for global data like user info, theme, language, or settings.

Context API = global data provider
useContext = hook to consume context inside functional components
Great for small to medium apps
For very large apps, combine with state management libraries like Redux or Zustand.
