Using useContext to manage global state in React applications
The useContext Hook is used to share application state data across the component tree without having to pass props down explicitly at every component level. To put it simply, useContext is a way to manage React applications’ global state. Remember, we used the useState Hook to manage local state in the Using useState to develop stateful components section.
However, as React project requirements expand in scope, it will be ineffective to use the useState Hook alone in passing state data in deeply nested components. The following is the syntax for the useContext Hook:

Briefly, we will discuss props drilling to understand the challenges it poses. Afterward, we’ll delve into the implementation of the context API, which addresses these issues.

Let’s examine how you might pass data as props down a component hierarchy without...
