how can create dynamic variable in angularjs view

Question

I want to do something like this in angular how can you do this?

$scope.test = "foo"; 
$scope.foo = "bar";

and in view

<span>{{scope[test]}}</span> <!-- and return $scope.foo that is "bar" -->

Answer 1

It should be with bracket notation:

<span>{{this[test]}}</span>

this points to current scope object, so with variable test beeing "foo", the expression will reference $scope.foo.
