May be Facebook would thought through this and they came up with a tool – create-react-app. This tools allows to create react app within no time.
I personally tried this tool for getting started with creating a HelloWorld react app and I did it in few mins!
create-react-app is a CLI which helps scaffolds all the required libraries and build frameworks and help us to focus on building the app without worrying on the setting up the project!
Here is the cool user guide on how to use this tool!
