var obj = new Object();
console.log(!!obj) // prints "true" even if it's empty
No. An object that doesn't have any properties assigned is not considered "empty".
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.
