Arrow function as constructor
const Animal = (name, age) => {
this.name = name;
this.age = age;
};
Animal.prototype.birthday = function () {
this.age++;
};
const animal = new Animal('Leo', 'Lion');
Bug Details
- Arrow functions don't have their own this keyword. So, adding properties will leads to Error.
- we can't add property on function prototype if it's arrow function. Again no this keyword.
- we cannot use new keyword on arrow function. This will throw error
X is not a constructor
