The documentation is very brief with this topic:
ng ejectejects your app and output the proper webpack configuration and scripts
What is the purpose of this command?

Webpack is a popular module bundler, a tool for bundling application source code in convenient chunks and for loading that code from a server into a browser. It's an excellent alternative to the SystemJS approach used elsewhere in the documentation.
If you aren't satisfied with the build tool and configuration choices, you can eject at any time. This command will remove the single build dependency from your project. Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc.)
Extend the Angular CLI's default build behavior without ejecting: 📄 Extend the default behavior by providing a partial config that just contains your additional settings. 📄 Alternative: Extend the default behavior by providing a custom function.
angular-cli is something magic, everything is done in a simple and automatic way.
But sometimes, you may want to act on how the package is done, add a plugin or you are simply curious to see the Webpack configuration on which it is based.
When running ng eject, you generate a webpack.config.json file. Looking at the file package.json you will see that the commands to launch have slightly changed:
ng serve --> npm start ng build --> npm run build ng e2e --> npm run e2 If you want to undo ng eject, you will have to edit your .angular.cli.json file and set ejected to false:
"project": { ... "ejected": false } ng eject basically get-rid of angular cli scripts and introduce webpack scripts in package.json, underlying webpack.config.js file mainly for comprehensive way to manage the project and it will be completely our responsibility to manage the project configurations after this.
A comparison of package.json scripts before and after is below,
