-Sometimes you will want your extension to wait for an "asynchronous" or "async" operation to complete before resuming instead of for your block to complete (almost) immediately. A common example of this is making a request: no matter how fast your internet is, any network request is not going to be instant.
+Sometimes you will want your extension to wait for an "asynchronous" or "async" operation to complete before resuming execution (versus resuming execution early and potentially causing problems).
