functional-shared-class.js

var Example = function() {
  var example = {};
  example.extraProp1 = "Example Property Value";
  _.extend(example, exampleMethods); // requires _ library or implement your own extend function
  return example;
};
 
var exampleMethods = {
  exampleGet: function() {
    return this.extraProp1;
  },
  exampleSet: function(value) {
    this.extraProp1 = value;
  }
};
