Constructor Function:

1. What is a Constructor Function?

​It is a special function used to initialize objects with specific values.

​It is called automatically when a new object is created using the new keyword.

​2. Naming Convention Rule:

​Regular functions start with a lowercase letter (e.g., function laptop()).

​Constructor functions start with an uppercase letter (e.g., function Laptop()).

​ Key Concept:

The this keyword refers to the current object being created.

​ Example Code:

function Laptop(brand, model, price, rom, ram) {
this.brand = brand;
this.model = model;
this.price = price;
this.rom = rom;
this.ram = ram;
}

const laptop1 = new Laptop("Lenovo", "l15", 45000, 512, 8);
const laptop2 = new Laptop("HP", "h15", 35000, 256, 4);

console.log(laptop1);
console.log(laptop2);
