Allan Jardine | Visual Event. When working with events in Javascript, it is often easy to lose track of what events are subscribed where. This is particularly true if you are using a large number of events, which is typical in a modern interface employing progressive enhancement. Javascript libraries also add another degree of complexity to listeners from a technical point of view, while from a developers point of view they of course can make life much easier!
