hw Instructions: Clone the repo Run npm install Run npm install -g nodemon Run nodemon in the proper directory. Go to http://localhost:3999/html/index.html Notes: I've used a queue mechanism to handle the rotation so it would be more smooth and so that events won't get in the way of each other. I haven't done validations on the server side on purpose, same goes for the AJAX calls I'm using. I've added some console.logs in places that I think that are relevant. I tried to write the code as simple and discriptive as possible. Please let me know if there's anything that's not clear.
