title: Is there an angular.noop for Angular 6?
body: <p>In my Angular 6 application, I need a function that does nothing. Obviously, I could just write my own, but I was reading about angular.noop which I would like to use. However, I get an <code>angular.noop is not a function</code> error when I try to use it. I could not find anything about this in Angular's documentation. Is there an Angular 6 version of AngularJS's angular.noop function?</p>
  
  <p>I know what noop is. This is not a duplicate of <a href="https://stackoverflow.com/questions/22348253/what-is-angular-noop-used-for">What is Angular.noop used for?</a>. I am asking about Angular 6. My question is very simply "Is there a noop function built into Angular 6 like there is in AngularJS?".</p>
