I'm pretty new to JavaScript, so this is just a note for wiser heads than mine.

Re this statement: Getters and Setters JavaScript writers can now add getters and setters to their objects. This feature is available only in the C implementation of JavaScript.

The actual section currently says nothing about being available only in C. This should be clarified.

Update: Similarly for the "Comments" item


You don't have to comment on all applicable talk pages :)
