Tell us what’s happening:

Can’t get the difference between using a function that returns an object and just define the object with the two functions as property. Pretty sure there is. By the way, this code passes the test.

Your code so far

let funModule =  { 
    isCuteMixin: function(obj) {
      obj.isCute = function() {
        return true;
      }
    },
    singMixin: function(obj) {
      obj.sing = function() {
        console.log("Singing to an awesome tune");
      }
    }
  }

I would say the difference is in the “immediately invoked” part of
“immediately invoked function expression”. It actively returns the object, but if you only define an object, it just exists, but nothing happens with it …
