Comment (by TimothyBlynJacobs):

 > defineProperty is unavailable in IE11, whereas __defineGetter__ is.

 @peterwilsoncc is it a particular part of `defineProperty` that isn't
 available? According to MDN it's available, https://developer.mozilla.org
 /en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty.

 > Reviewing other deprecated JavaScript code, the functionality is
 generally labelled as such in the docblocks but there isn't an equivalent
 of PHP's _doing_it_wrong() for JavaScript.

 It isn't a `_doing_it_wrong`, but we could potentially use the
 `deprecated` package:
