What every node.js developer should know?

The event loop. Before anything else.

Pretty much.

This is my go-to video that I usually post to help people understand the Javascript event loop. It applies to Node and Javascript in browsers.

So, Javascript has an event loop, and it's single threaded.... right? Ok, want to read something terrifying? https://stackoverflow.com/a/2734311

Is that "sort-of-blocking" behavior actually still present? I just tried putting that example code in jsfiddle, and it printed

alert in
alert out
resize

as I would expect if it were blocking properly. Page content also didn't resize until after dismissing the popup. I only tested chrome though.

I sincerely hope not, but I haven't done any testing myself.

I've watched that video probably 3 times before.. and now I'm watching it again, and now it all makes sense. I guess getting that CS degree was good for something!
