-  We identify the sort fields by text strings, expecting the pipe to reference a property value by indexing
-  (e.g., `hero['name']`).
-  Unfortunately, aggressive minification *munges* the `Hero` property names so that `Hero.name` and `Hero.planet`
-  becomes something like `Hero.a` and `Hero.b`. Clearly `hero['name']` is not going to work.

-  Some of us may not care to minify this aggressively. That's *our* choice.
-  But the Angular product should not prevent someone else from minifying aggressively.
-  Therefore, the Angular team decided that everything shipped in Angular will minify safely.

   filtering and sorting logic into the component itself.
   The component can expose a `filteredHeroes` or `sortedHeroes` property and take control
   over when and how often to execute the supporting logic.
   Any capabilities that you would have put in a pipe and shared across the app can be
   written in a filtering/sorting service and injected into the component.
