Poor IE performance

[tomByrer]

IE10's results were disappointing. I'm kinda bummed by my Android4.3 (Samsung Note2) results also, but not too worried. http://jsperf.com/chain-vs-pipe/6 Reduced results:

        Generic |  Lazy | Lo-Dash chain
Chrome31  2,153 | 4,109 | 4,862
Firefox24   784 | 1,005 | 1,027
IE10      1,710 |   909 | 2,910
Android4.3  272 |   523 |   701
IE8 VM       30 |    36 |    42

However, IE10 performance seems to be better against competition in another 1 width array test.

Edit: I tried the MS suppled VirtualBox for testing IE8. Even after turning on VT-x in my bios, & hacking the image's Registry to avoid IE script warning, it still performed worse than I remember IE8 ran on the same machine (which was bad). I would throw out my IE8 VM's results.

Gah! Thanks for bringing this up! Competitive side activated... ;)

:) Or atleast conditionally test for IE & copy/paste Lo-dash code if you can.

Maybe post on your README your jsPerf tests? That will help get more mobile & IE testing I hope.

If I understand correctly from jsperf test the "non-lodash-underscore-lazy" i.e. the "no-library optimized loop" approach gave 10x faster results with the only drawback is that it takes 10x LOCs
