Do I need a reverse proxy if I'm running a Node.js in a Docker container?

I've read some articles that recommend using reverse proxy (like nginx) before the Node.js application(like that one: Advantages of a reverse proxy in front of Node.JS). That is better (in terms of security at least) than running Node.js itself and exposing it.

However, running the Node.JS app inside a Docker container should prevent the security issues (because the app is running inside a container and is isolated from the host system).

So, my question is: are there benefits of using reverse proxy while running Node.js app in a Docker container? And if so, how can it improve my application?
