The problem is that "Silent Errors" is not spot on. At least not his example of them. If you have this example in angular, you'll get the same result.

$scope.myObj = {x: 2}; <div ng-bind="myObj.notHere"></div>

(forgive me if my syntax is off a bit, haven't written angular in awhile)

The example he gave is an object not having a properly on it that he's trying to access. Any javascript templating language will have this issue
