Why didn't we need to use async/await in this workshop at all? I often see it used with fetch.

Just wondering! I often get confused as to when async/await is needed and not needed when fetching external data like from an API.

Like many things in programming, there is often more than one way to accomplish the same thing. Since fetch is asynchronous by nature and returns a Promise, you can chain then methods to run at the moment of resolution instead of using await and coding the response in a separate statement. Both approaches are perfectly valid.

Another reason that await might have been avoided in this workshop is so it can be used by students who have not yet taken the Asynchronous Programming course.
