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
}

The null pointer was and is a billion dollar mistake that ruined among other things Common Lisp, Java and C#.
