示例代碼：

// First of all, we are going to declare a namespace for the class
$namespace.register("Joopl.Samples");

// Next part will be about designing the whole class
Joopl.Samples.Polygon = $class.declare(
// The constructor
function() {
    // This is very recommended: if you declare a class field in the constructor,
    // it will hold a default value instead of undefined
    this.$_.args = null;
},
{
  // Sets an object that will hold the arguments to calculate the polygon's area
  set_Args: function(value) {
    this.$_.args = value;
  },
  
  // Gets an object that will hold the arguments to calculate the polygon's area
  get_Args: function() {
    return this.$_.args;
  },
  
  // The method to calculate the area. Check that its body does implement nothing.
  // Derived classes will be the ones responsible of providing the formula to make the calculation.
  CalculateArea: function() {
  }
}
);
