JavaScript does have classes, but the way they are implemented is different from traditional class-based languages like PHP. JavaScript introduced a class syntax in ECMAScript 2015 (ES6), providing a more convenient and syntactic way to define object-oriented structures. In JavaScript, the class syntax is primarily syntactic sugar over the existing prototype-based inheritance system. The prototype-based approach allows objects to inherit properties and methods from other objects directly. The introduction of classes in JavaScript makes it easier for developers familiar with class-based languages to work with JavaScript. Here's an example of how classes are defined in JavaScript: javascript class Animal { constructor(name) { this.name = name; } makeSound() { console.log("Some generic sound"); } } class Dog extends Animal { constructor(name, breed) { super(name); this.breed = breed; } makeSound() { console.log("Woof! Woof!"); } } // Usage const myDog = new Dog("Buddy", "Labrador"); myDog.makeSound(); // Outputs: Woof! Woof! In the example above, Animal is a base class, and Dog is a subclass that extends Animal. The super keyword is used to call the constructor of the superclass. While JavaScript uses a prototype-based inheritance system at its core, the introduction of class syntax provides a more familiar and structured way for developers to work with object-oriented programming concepts. It's important to note that behind the scenes, JavaScript still utilizes prototypes for inheritance. read less
