Exploring the Code
Let’s explore the angular code and look at some important files within our new application.
Directory and file structure
Our previous code has a root file structure similar to the one below:
| exploring-angular | e2e | src | node_modules - angular.json - package-lock.json - package.json - README.md - tsconfig.json - tsconfig.app.json - tsconfig.spec.json - tslint.json - karma.conf.js
Look at this for reference.

Root directory
Most of these root files are configuration files that we won’t interact with much, if at all. We’ll modify a few later on in the course, we can leave them as-is for now. More detailed information on these files can be found online in the Angular QuickStart guide.
