syntax of 'element' argument on each() method in jQuery

in the following code: $('a').each(function(index,element){ console.log(index,$(element).attr('href')); });

why passing element argument to console.log() as "$(element)". and not simply "element". what are the $() stands for?

The each applies your function to each element as a key (stored in index) and its value (stored in element). In order to get the actual element from the DOM you need to convert the element value to the actual element, this is what $() does. It finds the actual element in the DOM referred to by the value in element and returns it so that you can examine its href attribute.
