Managing data access and state management becomes an increasing challenge as projects grow. The responsibilities of loading, updating and managing data in UI components can make UI code complex and unmanageable. The most common pattern for state management in a react app is through react-redux. React's useContext and useReducer is an another approach to managing application state. (There is a comparison of react-redux with useContext and useReducer in the Resources section at the end of this document.)

I'm 7 months into coding now, simply love React so I dedicated to write my tech article about it.
You can consider a 'classic' way of passing data, is passing data through a JSON list or Database.
This often causes having to re-deconstruct the State in each new child component.
To avoid this you can use the useContext hook in React, and pass it's props through a ContextProvider very easily.

Happy React useContext coding!
