/*In general, the 'this' references the object of which the function is a property.
In other words, the 'this' references the object that is currently calling the function.
Suppose you have an object called 'counter' that has a method 'next()'.
When you call the 'next()' method, you can access the this object. */

  count: 0,
  next: function () {
    return ++this.count;
  },
};
counter.next(); 
//Inside the next() function, the this references the counter
