Hi,

I continue my search to save bytes in jQuery.

My current target is the filter function which refers multiple times to

jQuery.expr[ m[1] ]

I stored this value in a var saving 17 bytes.

In the code there is also a resort call that moves the elements inside m to different indexes. However, it seems that the

m[1] 

This, even if dangerous in the long run (more resort functions can appear in the future moving the

m[1]

This last optimization consists in deleting the second f assignment

f = jQuery.expr[ m[1] ];
if ( f._resort )
  m = f._resort( m );
f = jQuery.expr[ m[1] ];

The "secure" patch is attached.
