What is the purpose of Wildcard route?

The purpose of a wildcard route in Angular is primarily to handle cases where no other routes match the URL requested by the user. This is often used to display a custom "404 - Page Not Found" error page or to redirect users to a default route when they enter a URL that does not correspond to any defined paths in the application.

A wildcard route is defined using a path consisting of two asterisks (**), which effectively matches any URL. This ensures that if none of the other routes specified in the application match the URL, the wildcard route will catch it. The typical implementation involves associating this route with a specific component, such as a PageNotFoundComponent, which is displayed when no other routes are matched[1][3][6].

For example, the configuration might look like this:

{ path: '**', component: PageNotFoundComponent }
