JavaScript Boolean Object Reference
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")!
