Javascript Question

Can an Object be false?

Is there any way to make an object return false in javascript?

var obj = new Object();

console.log(!!obj) // prints "true" even if it's empty

Answer Source

No. An object that doesn't have any properties assigned is not considered "empty".

The fact that a variable holds an instance of an object is enough to cause javascript to treat the variable as having the value of true when an expression requires a boolean value.


There are clearly some nuances to be cleared up looking at the other answers here.

null is not an object, it is the distinct lack of an object. The question refers to an Object, that is one that has just been created.
