var b = {};

var c = a || b;

alert(c);

The answer of this challenge question is [Object Object] but how?

Answer 1

That's just what is displayed when you alert() any object

Answer 2

The way I understand it is:
when you perform the above comparison "a || b" it is coercing "null" and "{}" into booleans. when coerced, null evaluates as false and objects as true. so "{}" wins the comparison battle and becomes the value set to var c.

Answer 3

The answer is [Object Object] twice

But I don't know why?
