Quiz Answers

1. When you use events, your scripts are no longer executed in the order that they are written in, as is the case with simple sequential scripts. Instead, event listeners are used to respond to events that occur, regardless of when they happen. This is liberating but initially requires a change in thinking about how you approach your code.

2. When your application includes network calls, you are often unable to predict exactly when something will return. As applications become more complex, it becomes much more manageable and efficient to structure code around events. When an event happens, a listener can respond to it!
