Hi Syed! In short, yes it is necessary to use webpack. All examples were created using my own custom react boilerplate (including webpack setup). I did not use create-react-app at all. The reason for not using create-react-app is because create-react-app does a lot of things "automagically" for you. I consider learning webpack an important skill to learning to work with React. Therefore, I setup webpack manually for all examples.
