Understanding JavaScript Classes

The constructor method is a special method that is automatically called when an instance of the class is created. It's typically used to initialize properties of the class.

class Animal {
  constructor(type, name) {
    this.type = type;
    this.name = name;
  }
}

const dog = new Animal('Dog', 'Buddy');
console.log(dog.type); // Output: Dog
console.log(dog.name); // Output: Buddy

    public function __construct($name) {
        $this->name = $name;
    }

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