Answer 1

I guess I'm not really understanding your design goals for this snippet and I only understood the first part of your post. What do you want the code to do?

Answer 2

I'm not really understand the code so.
However there are some errors I noticed, querySelector return a single element, not an array. Maybe you should use querySelectorAll which return all the assigned elements.
Other issues are
The index of the array is not initialize before use.
And the index does not reset based on the array length, would be runtime error when timer increase the index larger then the array length.
