AngularHintDirectives identifies directives that are undefined, most likely because of spelling errors. It provides suggestions of similarly spelled directives that are defined. For example, the code below has a simple spelling error that would prevent the list elements from being loaded. AngularHintDirectives warns that it found the nonexistent 'ng-repaet' directive and suggests that 'ng-repeat' might be the intended command.
<div>
<ul>
<li ng-repaet="i in [1,2,3,4]">{{i}}</li>
</ul>
</div>
