I need help with the AngularJS challenge after the video on Lists.

So I need help with the AngularJS challenge. It asks me to "Write the HTML to output an unordered list, or <ul>, that iterates over the array bowlOfFruit and outputs the property name for each array element as a list item." I cannot seem to figure out how to do this. Can someone help me? The tutorial videos were not very clear as to the structure of the content and in understanding the concepts of what went where.

index.html 
<!DOCTYPE html>
<html ng-app="myApp">
<head>
  <title>Angular.js</title>
  <script src="js/angular.js"></script>
  <script src="app.js"></script>
</head>
<body ng-controller="myController">
<ul>
  <li ng-repeat="name in bowlOfFruit" ng-class="name.bowlOfFruit" />
  {{bowlOfFruit.name}}

</body>
</html>
app.js 
angular.module('myApp', [])
.controller('myController', function ($scope, $http) {
  $scope.bowlOfFruit = [
    {name: 'Apple'},
    {name: 'Pear'},
    {name: 'Orange'}
  ];
});

So your <li> with the ng-repeat is on the right track. The bowlOfFruit looks to be an array of objects. When you ng-repeat( x in array) each individual array item will be iterated through, and named 'x'. In this case x will be an object, so you can address its properties with dot-notation like this: x.key, or in your example you would use the following:

<li ng-repeat="fruit in bowlOfFruit" />
  {{fruit.name}}
</li>

be sure to close your li and ul elements
