    JavaScript classes, introduced in ECMAScript 2015 (ES6), provide a more structured and object-oriented approach to creating objects. Classes in JavaScript are essentially templates for creating objects, encapsulating data with code to work on that data.

    Creating a Class

    To define a class in JavaScript, use the class keyword followed by the class name. Inside the class, you define a constructor method and other methods. The constructor method is a special method that initializes the object's properties when a new object is created.

    class Car {
    constructor(name, year) {
    this.name = name;
    this.year = year;
    }
    }
    Gekopieerd.

    In this example, the Car class has a constructor that initializes the name and year properties.

    Creating Objects

    Once a class is defined, you can create objects using the new keyword.

    const myCar1 = new Car("Ford", 2014);
    const myCar2 = new Car("Audi", 2019);
    Gekopieerd.

    Here, myCar1 and myCar2 are instances of the Car class.

    Methods

    Methods are defined on the prototype of each class instance and are shared by all instances. Methods can be plain functions, async functions, generator functions, or async generator functions. For more information, see method definitions.

    Static Methods and Fields

    The statickeyword defines a static method or field for a class. Static properties (fields and methods) are defined on the class itself instead of each instance. Static methods are often used to create utility functions for an application, whereas statiā€¦

    The example above creates a class named "Car". The class has two initial properties: "name" and "year". A JavaScript class is not an object. It is a template for JavaScript objects.
