Switch Statement to object

Tell us what’s happening:
Describe your issue in detail here.
I’ve converted a switch case statement to an object but there seems to be a problem. Any hints??

  **Your code so far**

// Setup
function phoneticLookup(val) {
var result = "";

// Only change code below this line
var lookup = {
  "alpha": "Adams", 
  " bravo": "Boston", 
  "charlie" :"Chicago", 
  "delta": "Denver", 
  "echo": "Easy", 
  " foxtrot": "Frank", 
};

// Only change code above this line
return result;
}

phoneticLookup("charlie");

You are halfway there. Now you need to use the object to update the result variable.
