Example 3: constructor in js
A constructor is a function that creates an instance of a class
which is typically called an “object”. In JavaScript, a constructor gets
called when you declare an object using the new keyword.
The purpose of a constructor is to create an object and set values if
there are any object properties present.

function Car(make, model, year) {
this.make = make;
this.model = model;
this.year = year;
