Inheritance Inheritance is possible using the call() method which invokes a method as though it were a method of the object specified by the first parameter function Person(first, last) { this.firstName = first; this.lastName = last; } Person.prototype.getFullName = function() { return this.firstName + + this.lastName; }; function Employee(first,last,position) { Person.call(this, first, last); this.position = position; } var eddie = new Employee( Eddie , Haskell , Schmoozer ); alert(eddie.firstName + + eddie.lastName + + eddie.position); But this doesn’t work yet: alert(eddie.getFullName() + + eddie.position);
