Thanks so much!
Two questions:
1: what are the performance benefits to using the second to the first
version of your code? I’m assuming that binding–then–currying will
have a performance hit over just currying.
2: what’s the best way of debugging javascript in IE? Obviously we
have Firebug for Firefox, but I can’t find anything remotely close
that does the trick.
Thanks,
Edd
