In the last exercise, we created a parent class named Animal for two child classes named Cat and Dog.
The Animal class below contains the shared properties and methods of Cat and Dog.
class Animal {
constructor(name) {
this._name = name;
this._behavior = 0;
}
get name() {
return this._name;
}
get behavior() {
return this._behavior;
}
incrementBehavior() {
this._behavior++;
}
}
The code below shows the Cat class that will inherit information from the Animal class.
class Cat {
constructor(name, usesLitter) {
this._name = name;
this._usesLitter = usesLitter;
this._behavior = 0;
}
get name() {
return this._name;
}
get behavior() {
return this._behavior;
}
get usesLitter() {
return this._usesLitter;
}
incrementBehavior() {
this._behavior++;
}
}
To the right, in main.js, you will put what you learned to practice by creating a parent class named HospitalEmployee.

Instructions
1.In the next few exercises, you will create two subclasses (Doctor and Nurse) from a parent class named HospitalEmployee. Below, we have listed the properties and methods you will find in the Doctor and Nurse classes.
Doctor
Properties: _name, _remainingVacationDays (set to 20 inside the constructor()), _insurance
Methods: .takeVacationDays()
Nurse
Properties: _name, _remainingVacationDays (set to 20 inside constructor()), _certifications
Methods: .takeVacationDays(), .addCertification()
In main.js, create a parent class named HospitalEmployee. Add a constructor with name as an argument.
2.Inside of the constructor(), set the instance’s _name to name and _remainingVacationDays to 20.
3.Under the constructor, create getters for your _name and _remainingVacationDays properties.
Inside the getter, return the property’s value.
4.Under the getters, add a method called takeVacationDays.
This method should accept one argument, called daysOff.
Inside the method, subtract daysOff from _remainingVacationDays. Save the result to _remainingVacationDays.
