I think your premature optimization disorder (POD) is flaring up again.
jQuery performance is something that should be understood but not obsessed
about. Is the code running in a tight loop? Is there
a perceivable performance problem? No? Move on please.
$( '<div>' ) or $( '<div />' ) ?
I think it's fine to choose one for consistency, but both are equally
performant[1]. and $( '<div>' ) has the benefit of being more brief.
Creating an element with attributes can be done like:
$( '<div>', { 'class', 'example' } );
It's important to note however that IE required that input and button tags
are created with a type (if they are going to have a specific one)
$( '<input type="password">', { 'class', 'example' } );
