... The Boolean object is an object wrapper for a boolean value. ... JavaScript 1.3: added toSource method . ... If value is omitted or is 0, -0, null, false, NaN , undefined, or the empty string ( "" ), the object has an initial value of false. All other values, including any object or the string "false" , create an object with an initial value of true. ... For Boolean objects and values, the built-in toString method returns the string "true" or "false" depending on the value of the boolean object. ...
