You are already familiar with an HTML class, but JavaScript also has a class. In JavaScript, a class is like a blueprint for creating objects. It allows you to define a set of properties and methods, and instantiate (or create) new objects with those properties and methods.

The class keyword is used to declare a class. Here is an example of declaring a Computer class:

Example Code
class Computer {};

Classes have a special constructor method, which is called when a new instance of the class is created. The constructor method is a great place to initialize properties of the class. Here is an example of a class with a constructor method:

Example Code
class Computer {
  constructor() {
  }
}

The this keyword in JavaScript is used to refer to the current object. Depending on where this is used, what it references changes. In the case of a class, it refers to the instance of the object being constructed. You can use the this keyword to set the properties of the object being instantiated. Here is an example:

Example Code
class Computer {
  constructor() {
    this.ram = 16;
  }
}

Here is an example of instantiating the Computer class from earlier examples:

Example Code
const myComputer = new Computer();
