how to iterate .each loop one recursion less

Question

I have an .each loop in jQuery.

I want to iterate the loop one time less. i.e if 4 elements are found matching, than the loop should iterate only 3 times.

PS: Not using var i and i++ etc. But actually looping 1 less.

Answer 1

Use the .slice( <start>, <end> ) method (negative end = offset relative to the end):

$(some_object).slice(0, -1).each( ... );
