title: Update angualar.js factory from chrome dev. tools
body: <p>Is there a way to override the downloaded <code>angular.js factory</code> from dev tools.
  <br/> I want to add some log statements from the client as I cannot do by deploying code. Normal Javascript functions could be updated easily just by running the updated function in console. <br/> But, I am unable to do that for <code>angular.js factories</code></p>
