Notify User upon change in any property of a certain element, takes the className as an input param for attatching the observer

GenericObserverNotification.js

const notifyMe = (className, title = 'Room status changed', body = 'Someone entered the room') => {
  var target = $(`.${className}`);

  const observer = new MutationObserver(function(mutations) {
    const notification = new Notification(title, { body });
  });
  // configuration of the observer:
  const config = { attributes: true, childList: true, characterData: true };
  // pass in the target node, as well as the observer options
  observer.observe(target, config);
};
