Current behavior

Parrt 3 of tutorial - MasterDetail. https://angular.io/tutorial/toh-pt2 heroes = HEROES; Browser error: Cannot find name ‘HEROES’. Studio code warning: [ts] Cannot find name HEROES as a warning If I replace with heroes:Hero[] = HEROES, it resolves.

On another minor ( but nonetheless important point)

Part 2 if tutorial: The Hero Editor https://angular.io/tutorial/toh-pt1

Quote- Add two properties to the AppComponent: a title property for the app name and a hero property for a hero named “Windstorm.”

At this point, the title property already exists. Adding of course will result in “Duplicate Identifier warning”. Pendantic I know, but good to get a tutorlal to follow without errors for us newbsters.

Expected behavior

Minimal reproduction of the problem with instructions

What is the motivation / use case for changing the behavior?

I got the same error but because I wrote: ‘heroes : HEROES;’. Error disappears when I corrected to ‘heroes = HEROES;’. Found the solution from: https://translate.google.ca/translate?hl=en&sl=ru&u=https://toster.ru/q/478059&prev=search

I had the same error where heroes = HEROES could not be found. However, once I restarted the server everything worked correctly.
