Checking for missing parameter in function

Question

Is this the correct way to check for a missing parameter in a function? Would this work in all browsers? How about IE?

function getName(name){
    name = name !=         


        

Answer 1

Yes this would work in all browsers though if you want to see if it is defined you might use:

function getName(name){
   name = typeof(name) !== "undefined" ? name : "default";
   return name;
}
