Undefined redux

A reader from Maynard asks:

My understanding is that in js, if a variable is declared var foo, and then it is read without an explicit initializer or setter being called, the variable still has a value of undefined and an error is signaled. If that is so in all js dialects then I don’t see any reason why adding variable declarations [to a class declaration] should ever cause problems. I don’t see how it could affect inheritance, for example. Am I missing something?

EMI gets it

Apple and EMI announced today that they will be offering music without DRM protection for an extra 30 cents. Huzzah! Someone finally gets it. Give your customer a fairly-valued product and you don’t have to treat them as criminals.

iTunes customers will be able to easily upgrade their entire library of all previously purchased EMI content to the higher quality DRM-free versions for just 30 cents a song
