Global State management:-

Global state management in React refers to the management of application-wide state that can be accessed and modified by any component in the application, regardless of its location in the component tree.

There are several popular libraries for global state management in React, including Redux, MobX, and Context API. In this answer, we will focus on the Context API, which is built into React and provides a simple way to manage global state.

The Context API allows you to create a context object that can be used to share state between components.

Props drilling:-
-----------------------
In React, props drilling refers to the process of passing data down the component tree by passing props through multiple levels of components. This can become an issue in larger applications, where components may be nested deeply in the component tree, as it can make it difficult to manage and maintain the flow of data.

Props drilling can be avoided in a few ways:

Context API: Context API allows data to be passed down the component tree without having to pass props through each level of component. The data can be accessed by any component that is a child of the Provider component.

Redux: Redux is a state management library that can be used to manage data in larger applications. It provides a centralized store where all the data is stored and can be accessed by any component.
