Answer 1

Use to use two ng-if expressions

<h1 ng-if="carname"> <a  href='link'>Go here </a>  </h1>
<h1 ng-if="!carname"> {{test}} </h1>

Answer 2

You need to use ng-if

 $scope.test ="123"
 $scope.carname = "Volvo";

HTML:

    <div ng-if="carname !== ''">{{test}}</div>
    <div ng-if="carname === ''">hard coded value</div>
