ngHref (directive in module ng )

Using Angular markup like {{hash}} in an href attribute makes the page open to a wrong URL, if the user clicks that link before angular has a chance to replace the {{hash}} with actual URL, the link will be broken and will most likely return a 404 error. The ngHref directive solves this problem.

The buggy way to write it:

<a href="http://www.gravatar.com/avatar/{{hash}}"/>

The correct way to write it:
