How to Reverse the Order of Iteration in jQuery\'s .each() Function?

Reversing the Order of .each() Iteration

When using jQuery's .each() function to iterate through a collection of elements, the order of iteration is usually determined by the DOM structure. However, certain scenarios may arise where you need to traverse the elements in the reverse order.

To achieve this, you can leverage the .get() method, which returns the collection as an array, and then employ the reverse() method to rearrange the array elements in descending order. By chaining the reversed array with the .each() function, you can iterate through the elements backward.

Here's an example:

$($("li").get().reverse()).each(function() {
  // Code to perform on each li item in reverse order
});

This code retrieves the li elements as an array using .get(), reverses the order of the array, and then uses .each() to iterate through the reversed array. As a result, the provided code would start with "Item 5" and proceed backward through the list.
