11,226,026 | I got confused with async nature of node.js. I'm writing a small project in it and my previous (sync) programming experience gets in the way.
How should I decide if/where to write async code?

] | You probably shouldn't. In most cases, you need async logic only when you're waiting for something from outside your application (mostly file, database and network operations). Delaying in-application code asynchronously will give you no performance advantage, as your code will still need to run *at some point*. | I already said that in comment, but I think it is a good idea to give examples as well.
The concepts of *callback* and *asynchrounous operations* are different, although related. The `forEach` loop you are using **is not** asynchronous at all. Here's how more or less the definition of `forEach` looks:
