The Boolean Object can only have a value of true or false.

Any of the following methods can be used to create a new Boolean object with an initial value of FALSE:

var bFalse = new Boolean()
var bFalse = new Boolean(0)
var bFalse = new Boolean(null)
var bFalse = new Boolean("")
var bFalse = new Boolean(false)

Any of the following methods can be used to create a new Boolean object with an initial value of TRUE:

var bTrue = new Boolean(true)
var bTrue = new Boolean(1)
var bTrue = new Boolean("true")
var bTrue = new Boolean("false")
var bTrue = new Boolean("any string")
