Yes, it is indeed possible to use classes in Node.js. Classes in JavaScript, including when used in a Node.js environment, provide a structured and reusable way to define and instantiate objects, encapsulating both data and behavior in a clean and manageable format.

Introduced with ECMAScript 2015 (ES6), the class syntax in JavaScript offers a more familiar and simplified way to create objects and deal with inheritance compared to the traditional prototype-based approach. In Node.js, classes are used as templates for creating objects, similar to other object-oriented programming languages. This feature is particularly useful for applications that require a clear structure for objects and their interactions, making the code more modular and maintainable.

For instance, classes in Node.js can be defined using either class declarations or class expressions. A class declaration involves using the class keyword followed by the class name and a class body enclosed in curly braces. Inside the class body, methods including the constructor can be defined[1][3].

Here is a simple example of a class declaration in Node.js:

class Rectangle {
    constructor(height, width) {
        this.height = height;
        this.width = width;
    }

    calcArea() {
        return this.height * this.width;
    }
}
