If there is any additional or missing information please let me know.
I want to make a new component in an existing angular app and I want to render that component to an existing page/component.
Problem:
The template does not appear to be getting used.
Steps:
1)created a component with the following command:
ng g c little-test
2)Followed error trail/debugged
3)got the app to run
4) no content from html file of component
My file structure:
application.component.ts:
