 ## Dealing with re-entrance
 
-In VS Code, commands defined by an extension are invoked asynchronously. It means that if multiple keystrokes are made quickly corresponding commands might be invoked concurrently. If a command consists of asynchronous operations such as using `await` for something but still needs to be serialized execution among other commands in the extension, we must deal with re-entrance.
