JavaScript Polymorphism Explained Simply
Polymorphism is the practice of designing objects to share behaviors and to be able to override shared behaviors with specific ones. Polymorphism utilizes inheritance in order to make this happen.
class Animal {
speak() { return "A sound"; }
}
class Dog extends Animal {
speak() { return "Woof"; }
}
class Cat extends Animal {
speak() { return "Meow"; }
}
for (const animal of [new Dog(), new Cat()]) {
console.log(animal.speak());
