In the terminal, what does the code mean?

The teacher seems not to explain the code meaning in terminal... 'node app.js john' (Sorry, I forgot the real name he used in the video) Does it mean Run the app.js and set a variable named john to it?

You're basically right. The first term is what you will run, in this case "node". The other terms are arguments to node.

Node then takes "app.js" to be the name of the file you want it to process (the JavaScript program). Anything left ("john" in this case) becomes arguments that are given to app.js.
