Chris Anderson commented on COUCHDB-57:
---------------------------------------
playing with Spidermonkey more and realized that my collect() is available
natively as myarray.map(). The unique() function should still be useful.
> Javascript helper functions for use in map and reduce functions

> I've been playing with Reduce, and enjoying it. I added a two functions:
> unique() and collect() - they are similar to sum() in that they transform
> arrays. Unique also has an option to provide a count of items found in the
> source array.
> I just wanted to share these function with everyone and suggest that a helper
> namespace be established in the view server to contain functions like these.
