Use Map shim with _.uniq

4

Rounding out my PRs for today: An alternative implementation of https://github.com/jashkenas/underscore/pull/2099, using a Map shim. [Performs](http://jsperf.com/underscore-uniq-hash-table-lookup/7) just as well, but simplifies `_.uniq` instead of making it more complex. This also...

Alias mapObject to mapValues

For the record, I like `_.mapObject` better. But this change was undiscussed. Re: https://github.com/jashkenas/underscore/issues/2061, 4f771e0

_.size to return symbol count of strings.

Continuing the [discussion](https://github.com/jashkenas/underscore/commit/bdb06bcfcdcc85bfe3b494d9907762945f7d7c49#commitcomment-13243061), at the moment: ``` js _.size('💕') // => 2 ``` Since `str.length` is trivial I think it --may-- be handy if `_.size` returned the number of symbols...

Expand support for methods used as iteratees.

3

Methods like `_.sample`, `_.first`, `_.initial`, `_.last`, & `_.rest` have guards to support being used as an iteratee for methods like `_.map`. I think it'd be great if this was expanded...

Make the underscore wrapper iterable

1

Thoughts on making the Underscore wrapper an iterator and iterable? It would require detecting `Symbol.iterator` and doing something like ``` js _.prototype[Symbol.iterator] = function() { return this; }; _.prototype.next =...

iterator support for _.toArray

5

I think support for converting iterators to arrays would be a nice to have for `_.toArray`.
