/*Note: Directly assigning to FunctionName.prototype removes its original prototype's "constructor" property. As a result, (new WorkerBee).constructor yields "Employee" (instead of expected "WorkerBee"). Care must be taken to preserve the original prototype's constructor. For instance, assign the parent to FunctionName.prototype.__proto__ instead. For example, WorkerBee.prototype.__proto__ = new Employee; This way, (new WorkerBee).constructor yields expected "WorkerBee".*/
