title: Angular binding equivalent of a FallbackValue?
body: <p>So in XAML there's a handy little binding base attribute you can set called <code>FallbackValue</code> that I use often when designing in instances where I may not have data immediately available but also don't need to actually go set up design time data either.</p>
  
  <p>I'm trying to find if there's an equivalent to this in Angular binding I can use for the same purpose. Basically just a quick/simple way to have some display data when the binding fails?</p>
  
  <p>Like in XAML <code>Text="{Binding Blah, FallbackValue=FAIL}"</code> would display FAIL if there's no data. Is there a one liner equivalent for Angular as well? So far my searches haven't found a solution but maybe I'm just not using the right nomenclature. Thanks</p>
