Create a Boolean Object
The Boolean object represents two values: "true" or "false".
The following code creates a Boolean object called myBoolean:
var myBoolean=new Boolean();
If the Boolean object has no initial value, or if the passed value is one of the following:
- 0
- -0
- null
- ""
- false
- undefined
- NaN
the object is set to false. For any other value it is set to true (even with the string "false")!
