jQuery each2 plugin vs jQuery core .each method (v32)

Revision 32 of this benchmark created by Yukulélé on

Description

Basically, if you're going to do $(this) inside an .each loop, you should consider using the jQuery each2 plugin instead, because it's specifically optimized for this extremely common use case!
