Object-Oriented Programming Development Tutorials, Guides & Insights

JavaScript has evolved significantly over the years, and one of the key features introduced in ECMAScript 6 (ES6) is the concept of classes. While JavaScript has always been an object-oriented language, the introduction of classes brought a more familiar syntax for developers coming from other object-oriented programming languages like Java, Python, or C#. In this tutorial, we'll explore JavaScript classes in depth, including how they work, why they're useful, and how to effectively use them in your code.

This tutorial assumes a basic understanding of JavaScript, including functions, objects, and inheritance. If you're new to these concepts, it may be helpful to review them before proceeding.

// Define a Person class
class Person {
    // Private property to store the person's name
    private $name;

    // Constructor to initialize the person's name
    public function __construct($name) {
        $this->name = $name;
    }

    // Method to greet the person
    public function greet() {
        return 'Hello, my name is ' . $this->name;
    }
}

// Create an instance of the Person class with the name 'Alice'
$person = new Person('Alice');

// Call the greet method and echo the result
echo $person->greet();
