I had a need for Dictionary for my purposes as well (i.e. using Objects as keys).
I just implemented ObjectMap which wraps Map, WeakMap and Dictionary. It falls back to plain objects for browsers which do not support Map and inserts uids into the objects. It’s not tested yet, but it compiles. I expect to test it in the next few days. > On Feb 10, 2017, at 1:33 AM, Alex Harui <aha...@adobe.com> wrote: > > Also consider whether you truly need Dictionary or not.
