var Basket = function() {
  this.count = 5;
};

Basket.prototype.count = 1;

var x = new Basket();
console.log(x.count); // 1 or 5? (and why?)

// and
var Basket = function() {};
Basket.prototype.count = 1;

var x = new Basket();
x.count = 5;
console.log(x.count); // 1 or 5? (and why?)

@chinchang The second case would also log 5 for the same reason as the first case. x is the object returned by the constructor function, not a reference to the function so it would try to access x.count and find it before looking for x.__proto__.count

The two examples are essentially equivalent.

@mrappleton Ahh...my bad :) you are right.

Sorry for the confusion @chinchang @mrappleton - I made a mistake in my example facepalm. The second example was wrong - as you point out setting Basket.count doesn't really do much of value. Updated it now.

haha. I was wondering how come I wrote the second O/P wrong :P
