Success! Created sumit-app at /Users/esumit/Documents/ReactSumit/sumit-app

Inside that directory, you can run several commands:

  yarn start

    Starts the development server.

  yarn build

    Bundles the app into static files for production.

  yarn test

    Starts the test runner.

  yarn eject

    Removes this tool and copies build dependencies, configuration files

    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd sumit-app

  yarn start

Happy hacking!
