Creates a new Boolean value.
var variablename = new Boolean(boolvalue)

The optional boolvalue argument is the initital Boolean value for the new object. If this value is omitted, or is false, 0, null, NaN, or an empty string, the initial value of the Boolean object is false. Otherwise, the initial value is true.

The Boolean object is a wrapper for the Boolean data type. JScript implicitly uses the Boolean object whenever a Boolean data type is converted to a Boolean object.

You rarely call the Boolean object explicitly.
