What are the differences in angular controller notation?

Question

I\'ve have seen a couple of notations to initialize a controller in angular, those are:

app.controller(\'nameCtrl\', function($scope, ... ){})

Answer 1

app.controller('nameCtrl', function($scope, ... ){})

The above won't work with minification, but the below will.

app.controller('nameCtrl', ['$scope','...',function($scope,...){}])
