React useContext: A hook to make the use of react context more reader-friendly

useContext-

const value = useContext(MyContext);
Context is designed to share data that can be considered “global” for a tree of React components, such as the current authenticated user, theme, or preferred language.
  1. A Context provides both a consumer and a provider. When using the useContext Hook in React, one important thing to remember is to pass the whole context object, not just the consumer or provider.
  2. As mentioned in the official documentation, component calling useContext will always re-render when the context value changes. If re-rendering the component is expensive, you can optimize it by using memoization. We will cover about memoization later in the series while discussing useMemo().
