Why ES6 > * (but not really)

class.es5.js

var inherits = require('utils').inherits
var Model = require('some-orm').Model

function User () {
  Model.call(this)
}

inherits(User, Model)

Model.prototype.getName () {
  return this._name
}

classes.es6.js

let Model = require('some-orm').Model

class User extends Model {
  get name() {
    return this._name
  }
}

prototypical.js

var Model = Object.create(null); // you didn't actually specify any properties...

var User = Object.create(Model, {
  name: { // same syntax as defineProperty. extra newlines for clarity.
    get: function() {
      // getters/setters like this are unnecessary, but whatever, I'll just assume it's placeholder code.
      return this._name;
    }
  }
});
