0 is false, `''` is false; they are both false (0), that's why. – Derek 朕會功夫 Mar 28 '13 at 17:05

That is because javascript is attempting to do a type conversion on '' since '' is a type String and 0 is a number type. '', when converted to a number, is 0

2there is no conversion to a `Boolean` here. The _result_ of the `==` operation is a boolean, though. – Alnitak Mar 28 '13 at 16:54

Yeah sorry I realized that was incorrect after I wrote it. Thanks for the tip, I edited my response - doesn't matter since the question is closed now anyways. – What have you tried Mar 28 '13 at 16:57
