What does this this ActionScript syntax mean? ( Syntax for returning Objects Inline )

public function getData(node:Object, model:Object=null):Object
	{
		if (node is Office) {
			return {children:{label:node.name, label:node.address}};
		}
	}

return {children:{label:node.name, body:node.address}}

var obj:Object = new Object();
obj.children = new Object();
obj.children.label = node.name;
obj.children.body = node.address;
return obj;

var myobject = {
   'prop1': 100,
   'prop2': {
      'a': 1
   }
}

trace( myobject.prop1 );   // 100
trace( myobject.prop2.a );   // 1

return {children:{label:node.name, label:node.address}};
