Thanks @steve-jansen!

Instead of adding an argument for the callback function, wouldn't it make more sense to return the value in a try...catch block? For example:

try {
  console.log(zlib.gzip('Hello, world!'));
} catch (e) {
  throw e;
}

You're completely right, I'm a UI dev and I've only ever used Javascript in the browser – it just seems like adding callback arguments to NodeJS methods adds cruft to methods that could easily be implemented with native functionality. Thanks for taking the time to help me understand!
