How to write an if statment where an array is empty

1

Ok I’m trying to write an if statement say that if the array is empty goto frame 1. I’m trying different things for this and I cant seem to get it. The only thing i can get so far is this…



if(myArray.length = -1){
   _root.gotoAndPlay(1);
   trace(myArray);
}

But that doesnt work, cause when you click the button even if the array isnt empty it still takes you to frame 1 :S. Can someone please help me.
