JavaScript Boolean Object
Boolean Object
The Boolean object represents two values: "true" or "false".
Syntax
| 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")!
