Welcome! Today’s goal is to harness the Context API to overcome a common challenge — managing real-time interactions in React.js applications. Achieving simplicity and clarity in code often leads to better maintainability, and the Context API is designed to help us do just that.

State management in React.js can often be complex. The useState Hook is a superb tool, but it manages local states. When it comes to sharing data between multiple components, the practice known as “prop drilling” can result in hard-to-maintain code. Prop drilling is a process in React where props are passed from one part of the tree to another by going through other parts that do not need the data, but only help in passing it around. For larger applications, passing props through multiple layers can become messy and make the code base quite hard to maintain. This is the problem the Context API is designed to solve.

The Context API simplifies state management. It employs the createContext function and a context object, which encompasses both the Provider and the Consumer. While the Provider grants access to context data, the Consumer uses the useContext Hook to consume that context data - quite a symphony, indeed!
