Answer 1

You are only defining the function helloworldapp , not calling it.

do helloworldapp() to execute the function

Answer 2

If this is everything you put in the app.js file, you are not calling your function.

function helloworldapp() {
  console.log("Hello world");
}

helloworldapp()

I suggest you follow the nodejs getting started guide. https://nodejs.org/en/docs/guides/getting-started-guide/
