I was trying to test the performance of my React app(created with create-react-app) with react CDN script and i did 'npm run eject' to add webpack externals dependencies react and react-dom.
I did that with ease in webpack config and <script> in index.html
... externals: { react: 'React', 'react-dom':'ReactDOM' }, ... Now I want to revert it back to previous state
I am using git and i did this experiment in a seperate branch.
I ran git checkout master and npm start
The result was annoying
