Jquery function . date

Question

Can anyone enlighten me or explain to me the difference between these two situations

$.data(this, 'timer')

Or

$(this).data('timer');

Answer 1

In the documentation this is confirmed:

Note: This is a low-level method; a more convenient .data() is also available.
