Actual fact is i would like to store this outer array into a variable and use it inside the loop.

for instance

if(key==='data'){
	var test = outer;
}

Open in new window

			angular.forEach($array, function(outer, key) {			
				if(key==='data'){
				     var test = outer;
				}
				if(key==='try'){
					angular.forEach(outer, function(outerItem, key){
						 $module_name = outerItem.name; 
						 //console.log($module_name);
						 angular.forEach(outerItem.permission, function(outer_perm, key) {	
						         console.log(test); 
						 });
					});
				}
			});

However I keep getting undefined message.

Your code relies on the "data" key to be processed before the "try" key in the object, but the order of the items when you iterate them is undefined, and the order actually differs between browsers.

If you know that the items exists, you could just pick up the value from the object before the loop:

var test = $array.data;
