Create a Boolean Object

The Boolean object represents two values: "true" or "false".
The following code creates a Boolean object called myBoolean:

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")!
