### The Road Behind
We travelled a great distance in this chapter.
- We added the Angular *Component Router* to navigate among different components.
- We learned how to create router links to represent navigation menu items
- We used router parameters to navigate to the details of user selected hero
- We shared the `HeroService` among multiple components
- We learned how to create router links to represent navigation menu items.
- We used router parameters to navigate to the details of user selected hero.
- We shared the `HeroService` among multiple components.
- We moved HTML and CSS out of the component file and into their own files.
- We added the `uppercase` pipe to format data
- We added the `uppercase` pipe to format data.
