Hi Mark,
Usually, there is a separate module file that imports all the other modules, mainly know as ‘app.module.ts’ file. And, the app.component.html and app.component.ts files are used to create a separate component but it is usually the first component to be shown. In our examples, we have combined the app.module.ts and app.component.ts file for simplicity because our examples do not use the angular-cli project. Instead, they use the SystemJS module loader for loading the files.
I hope that this clears your doubts but if you have any additional queries, feel free to ask us.
Regards,
Ashwin
