     Because JavaScript objects are not constrained to predefined interfaces as they are with .NET objects, you can set expando properties on any object.

   • 2010, Alexei White, JavaScript Programmer's Reference:

     I talk more about expandos in Chapter 10. This means that you can arbitrarily add new properties to an object whenever you want.
