AngularJS - How can I reference the property name within an ng-Repeat

Question

In addition to rendering the value of the properties in an object, I'd also like to render the property name as a label. Is there a way to do this with ng-repeat? For example:

<ul>
    <li ng-repeat="option in data">{{propertyName}}: {{option}}</li>
</ul>

Which might spit out something like this:

<ul>
    <li>Name: John</li>
    <li>Phone: (123) 456-7890</li>
    <li>Country: England</li>
</ul>

Answer 1

Try this:

<ul>
    <li ng-repeat="(key,val) in data">{{key}}: {{val}}</li>
</ul>

Answer 2

The problem with documentation is that it says (key, value) with that space ... it took me some time to figure out that because of that it doesn't work
