Not sure I understand the usage attributed to Netflix? Sounds like the writer is saying that front end is node, but that can't be right? Can someone who knows what they're using node for go into a little more detail?

Not sure I buy the argument.
The more time goes by the more I feel crazy for missing whatever would motivate people to use js for anything more than is strictly necessary. Single threaded server??? I mean come on man, I understand you don't need parallelism for a lot of use cases but even if that fits your situation why javascript? It can't be that hard using a different language. I refuse to believe that.
I've never written anything on node.js, but that's the only argument that's ever given me pause.

I think a few aspects of the language contribute to this: 1. It is relatively easy to comprehend and pick up and play around with. 2. With the advent of node.js, and later electron, it is incredibly relevant whether you're developing web apps, servers, or now, even desktop apps. 3. Some of the newer features, such as arrow functions actually make writing javascript a lot of fun! JS has come a long way. I do think the…
while (true) { var d = new Date; e.textContent = d.toLocaleString(); }
I was an idiot, but at the same time, an unprivileged process should not be able to consume resources like that without a dæmon coming in and pausing/killing it. And the Javascript should not have been allowed to execute once I had closed the window.
Truly, Javascript is eating the world.

In many large orgs devs still use a homogenous tool for the existing systems (e.g. my guess is at Netflix all new business logic services are still Java based to plug into the Spring+NetflixOSS stack).
Meanwhile, trying to find Go developers can be a challenge. And the learning curve is low, but there's plenty of low-level gotchas like dealing with concurrency and memory usage. (Yes, even in a garbage collected language, this manages to be a problem.)
In Node, you run into less issues because if you have a problem to solve you just npm install something.
That being said, my enthusiasm ends there. Every experience I have with trying to tie a database into Node has been horrible. Also, I think event loop based programming is missing the mark even if it beats out previous methods; I think Go and other CSP based languages like Erlang have the real right answer. I think if we really start seeing huge core counts, it will become apparent that a single thread event loop eventually starts to become a bottleneck. Also, NPM has an insane number of packages, but the quality is extremely variable - much more than PyPI, though I'm not saying everything on PyPI is magically production ready.
I guess what I'm saying is, maybe I should start learning Rust.
