[jQuery] Something equivalent to Prototype's Class.create() ??

[jQuery] Something equivalent to Prototype's Class.create() ??


Hello all,
I've googled this topic...
I found one page that was an April Fool's joke but I'm not entirely
sure if it's legit or not?
http://ejohn.org/blog/classy-query/
Then there's Low Pro at:
http://www.danwebb.net/2008/2/3/how-to-use-low-pro-for-jquery
So is there a final version that's included in jQuery or does it have
to be included separately (i.e. one of the two above - or is there an
even better version out there?)
Thanks,
Shao
