Just use the length property of a JavaScript array like so:

$scope.names.length

Also, I don't see a starting <script> tag in your code.

If you want the length inside your view, do it like so:

{{ names.length }}

You can find the number of members in a Javascript array by using its length property:

var number = $scope.names.length;
