Sorry for dump, question, I am new to `AngularJS` and to `JavaScript`. I would like to iterate over collection by clicking the button.

```
<body ng-init="customers = [
{'name':'John', 'city':'Doe'},
{'name':'Anna', 'city':'Smith'},
{'name':'Peter', 'city':'Jones'}
]">

<div class="container" ng-app="myApp" ng-controller="myCtrl" >
    <div class="span12">
        <h1>{{name}}</h1>
        <br/>
        <p>{{city}}</p>

        <button type="button" name="button" value="Next" ng-click="makeIterator($scope.customers)"></button>
    </div>
</div>

```

So after clicking `Next` button I would like to see next iteration of customers displayed. How could I make it?
