+// prototype pattern
+// The Prototype Pattern is a design pattern in JavaScript that allows objects to inherit properties and methods from other objects, known as prototypes. 
+// It promotes code reuse and helps conserve memory by allowing objects to share common properties and methods through inheritance.
+
+
+// We will see two example:  
+// 1. using simple object   
+
+var person = {
+    greet: function() {
+        return "Hello, my name is " + this.name;
+    }
+};
+var person1 = Object.create(person);
+person1.name = "Bittu";
+
+var person2 = Object.create(person);
+person2.name = "Rajesh";
+
+console.log(person1.greet()); // Hello, my name is Bittu
+console.log(person2.greet()); // Hello, my name is Rajesh
+
+
+//2. using constructor function 
+function Car(make, model, year) {
+    this.make = make;
+    this.model = model;
+    this.year = year;
+}
+Car.prototype.displayInfo = function() {
+    return `This is a ${this.year} ${this.make} ${this.model}.`;
+};
+
+var car1 = new Car("Toyota", "Camry", 2020);
+var car2 = new Car("Honda", "Civic", 2018);
+
+console.log(car1.displayInfo()); // This is a 2020 Toyota Camry.
+console.log(car2.displayInfo()); // This is a 2018 Honda Civic.
