The first argument to the$.each() method is the array or object to iterate over, with the second argument being the callback method that is executed for each element. (Note that this is slightly different from the jQuery collection method $('div').each(), whose first argument is the call back function.)
When the callback function defined by the developer is executed, the this variable is set to the value of the element currently being iterated. Thus, the previous recipe could be re written as follows:
