My thoughts.

edit: added lazy.js to the benchmark and transducers.js wins hands down. Lazy also starts way behind _/lodash and only catches up after >50k elements.

What about transducer support in David Nolen's mori library?

I would be interested to know how its transducer support and performance compares to transducers.js.
