Angular: I don't understand the question in the context of the video.

Here's the code as I've written so far. The question asks,

Write the HTML to output an unordered list that iterates over the array bowlOfFruit and outputs the property name for each array element as a list item.

But i've been through the video twice and i can't seem to make the connection between the challenge and the video.

To iterate, I can only assume it means the ng-repeat directive and to output the correct valur you'd type {{user.nbowlOfFruit}}. But what am I missing?

Thanks

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">{{name.bowlOfFruit}}</li></ul>

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

You're very close. In your ng-repeat directive, since you are saying name in bowlOfFruit the expression would be {{name.name}}.

A better option for your directive might be fruit in bowlOfFruit so the expression would be {{fruit.name}}.

I was bit struggling with it too, found solution here: https://docs.angularjs.org/api/ng/directive/ngRepeat.

Correct answer will be:

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