/*
 * Author : Jaydatt Patel
class syntax:
1)  class class_name{
            variable declaration...;
            constructor(){.........}
            methods(){........}
        }

2)  const class_name = class {
            variable declaration...;
            constructor(){.........}
            methods(){........}
        }

You can also add prototype for class same as constructor function.
