title: Why does $scope in angular logs as 'b' and its parent as 'm'
body: <p>This might be more of a theoretical question, but I noticed that in my AngularJS app (v. 1.5.7), when console.log($scope) is done in a controller, it prints as an object with a label 'b'. </p>
  
  <p>It's 'parent' prints with a value 'm'.</p>
  
  <p>Is there some reason for this? Any significance to this?</p>
