Javascript Boolean

The Boolean object is an object wrapper for a boolean value.

Syntax

new Boolean([value])

Parameters

value
Optional. The initial value of the Boolean object.

Any object whose value is not undefined or null, including a Boolean object whose value is false, evaluates to true when passed to a conditional statement. For example, the condition in the following if statement evaluates to true:

var x = new Boolean("false");
if (x) {
// this code is executed
}

Uh, you're using a STRING as an argument for the Boolean constructor. What if you instead used
var x = new Boolean(false);

EDIT: Just tested in node.exe, apparently a var assigned "new Boolean(true)" evaluates to true, however the negation of a var assigned "new Boolean(false)" evaluates to false.
