slice   isn t always better  In my case  with jQuery 1 7 in Chrome 36   slice 0  20  failed with error   RangeError  Maximum call stack size exceeded  I found that  lt 20  worked without error in this case  I had probably tens of thousands of matching elements

I found this note in the end of the lt   docs      Additional Notes       Because  lt   is a jQuery extension and not part of the CSS specification  queries using  lt   cannot take advantage of the performance boost provided by the native DOM querySelectorAll   method  For better performance in modern browsers  use    your-pure-css-selector   slice 0  index  instead    So use    selector   slice from  to  for better performances
