https://developer.mozilla.org/en/Firefox_for_developers tells us about
Firefox 12: "Experimental support for ECMAScript 6 Map and Set objects
has been implemented.".
The pages it links to,
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Map
and
https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Set, however
state that the feature is (respectively will be?) implemented in Firefox 14.
When I try
typeof Set
in Firefox 12's web console I get undefined so the feature does not seem
to be available, unless I first need to enable it with some JavaScript
version setting.
So why does https://developer.mozilla.org/en/Firefox_for_developers
suggest that Map/Set is supported?
