Enable JavaScript WeakMap
Project Member Reported by, Sep 22 2011 Back to list
The WeakMap implementation in V8 is now finished

We should enable it in Chromium too.

WeakMap was enabled in Firefox 6.

I think it's premature to enable the flag by default. It's prudent to wait at least until the feature shows up in the specification working draft and until it has cooked enough so that we don't encourage folks to write code that will later break. There are also still some open issues with the WeakMap implementation (as with all of our Harmony support right now).
