Okay so maybe this is a dumb question, but how to read, for example, msg.topic in .js file, for ( i want to log msg.topic to console)?
Done a lot of search on this, and trying reading from some other nodes, but I am a little confused.

Well in my custom node i want to use msg.topic from input (string (ip or domain )) and save it to var address.

If you look at the lower-case.js example in the node red docs [creating your first node](https://nodered.org/docs/creating-nodes/first-node) it shows how to access `msg.payload`. `msg.topic` can be accessed in exactly the same way.
