The Boolean Object

The Boolean object represents two values: "true" or "false".

Syntax for creating a Boolean object:

var myBool=new Boolean(value)

Note: If the value parameter is omitted, or is 0, -0, null, "", false, undefined, or NaN, the object is set to false. Otherwise it is set to true (even with the string "false")!
