Question

The below code gives me two alerts one after the other – Hello1234 and undefined

var b ={ status:"Ready" ,
         deep : { a:12 , b:"String" ,
                  c:function() {alert("Hello1234");
                               }
                 }  
        }

alert(b.deep.c());

Could anyone let me know why does that happen ?

Answer 1

This happens because:

1. b.deep.c() has a call to alert inside it.
2. the return value of that method is not defined, but you attempt to alert the return value, so get [the string representation of undefined] undefined.
