What is State Management?

Beginning from React 16.8, every React component, both class and functional ones, can have a state. To put it simply, State is a JavaScript object that represents the components Memory. It can be changed anytime as a result of users actions or events. State can be passed down the component tree in a process called props drilling.

As the app gets bigger it becomes more and more difficult to manage state and props drilling makes it harder to keep track of all dependencies. A better solution is to simply separate the state from the app using Context API and then share it where it is needed.
