example:

class Animal {

}

get name() {

return this._name;

}

get behavior() {

return this._behavior;

}

}

get name() {

return this._name;

}

get behavior() {

return this._behavior;

}

get usesLitter() {

return this._usesLitter;

}

incrementBehavior() {

this._behavior++;

}

}

//cat inherits the properties from animal class which is parent class
