Use an IIFE to Create a Module

Use an IIFE to Create a Module

Method

Both Mixin's must be wrapped in a new funModule so an esay starting point is to comment out all the code so far.

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

Then below start writing your new funModule code. Inside the new module, you need to write a return statement to return both Mixin code blocks. Simply copy both original Mixin code blocks into your new module code, but remember to seperate both mixins with a ,

Solution

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