Why change page title

Changing the page title is very important as it helps the search engines to know the purpose of the page and index it properly. It also helps users to know, which page they are in.

Being a single page app, the angular does not reload the entire page. The page is loads only once at the startup. Only part of the page gets loaded when you navigate from one route to another.

The title of the page is set in the index.html as shown below. We use the HTML title tag to set the title of the app. Since it is loaded only at the start, all other pages or routes get the same title.
