The Instance properties must be defined inside of class methods. For example, name and age properties defined inside constructor as below,
class Person {
constructor(name, age) {
this.name = name;
this.age = age;
}
}
But Static(class) and prototype data properties must be defined outside of the ClassBody declaration. Let’s assign the age value for Person class as below,
Person.staticAge = 30;
Person.prototype.prototypeAge = 40;
