JavaScript Boolean constructor Property

The constructor property returns a booleans's constructor function:

var bool = false;

Definition and Usage

The return value is a reference to the function, not the name of the function:

For JavaScript numbers the constructor property returns function Number() { [native code] }

For JavaScript booleans the constructor property returns function Boolean() { [native code] }
