function superclass() {
  this.info = alert("Defining the Superclass");
}

function subclass() {
  this.inheritFrom = superclass;
  this.inheritFrom();
  this.info = alert("Overriding the Superclass");
}

To activate the generation of subclass(), click here. This button calls the following function:

function createSubclass() {
  var newClass = new subclass();
}

Notice the alert boxes. They show that the info method is first defined in superclass() and then is being overridden in subclass().
