Classes in Javascript are templates used to create objects.
Game class.Game class.Class inheritance in Javascript lets us create a new class as the child of another class (the parent). This allows code to be more efficient and concise. This is because we can reuse previously-created class elements in a new class without having to rewrite the same code.
Class inheritance utilizes two keywords: extends and super.
The extends keyword signals that the new class is inheriting the properties of the parent class.
The super keyword signals that the enclosed property or method is being inherited from the parent class.
//Game classclass Game {constructor(name, maxNumberOfPlayers) {this.name = name;this.maxNumberOfPlayers = maxNumberOfPlayers;}}//The Videogame class inherits properties from the Game classclass Videogame extends Game {constructor(name, maxNumberOfPlayers, platforms) {super(name, maxNumberOfPlayers);this.platforms = platforms;}}//Creates two new videogame objectslet newVideogame1 = new Videogame("The Legend of Zelda: Breath of the Wild", 1, ["Nintendo Switch"]);let newVideogame2 = new Videogame("Stardew Valley", 4, ["PC", "Nintendo Switch", "Android", "PS", "XBOX"]);console.log(newVideogame1.name);//Prints The Legend of Zelda: Breath of the WildnewVideogame2.platforms.forEach((p) => {console.log(p)})//Prints://PC//Nintendo Switch//Android//PS//XBOX
