Question

1. Add a plugin to the real jQuery library so that when you pass an array of elements to it, the function can move the elements forward and backward repeatedly. Then test your plugin by sending an array of images to it.

Answer 1

solution:

given data:

As per what I understood, you want to modify the original jQuery library and add some method that can be called on your Array list to move the elements to and fro (forward and backward).
If this is the case, you can even try adding methods to the Array prototype in the following syntax:
Array.prototype.<function_name> = function(){
//some code.
};

Here <function_name> can be replaced by moveElements and then you can go ahead and add the logic to move the elements forward and backward as per your convinience.

This is the walkthrough of how you can acheive your desired output.
