HTML markup for AngularJS views

I am working my way through "AngularJS Starter" which is a 51 page book by Dan Menard. Some of the syntax examples in his first example of a view include:

1. Here is a typical ng-repeat loop with a filter which refines how the results are ordered.
   <li ng-repeat='note in chapter.notes | orderBy"id"'>
    
2. This could be done inside the loop:
   <p>{{note.content}}</p>
    
3. This could be a link inside the loop:
   <a href ng-click='onDelete(note.id)'>delete</a>
    
4. A link to another route:
   <a href='#/addNote/{{chapter.id}}'>add note</a>
    
5. Showing or hiding copy conditionally:
   <span ng-show='chapter.notes.length == 1'>note</span>
   <span ng-hide='chapter.notes.length == 1'>notes</span>
