The other day I managed to freeze my computer -- such that I did not even have access to the SysReq key, by stupidly running while (true) { var d = new Date; e.textContent = d.toLocaleString(); } I immediately realised my stupidity, and closed the tab. Shortly after, my mouse froze up, then my keyboard access, and eventually my entire access. Rather than just freezing Xorg as I had initially suspected, it froze my en…
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.
With ES6, JS became a really nice scripting language. Personally, I'm glad to see more and more projects that use javascript outside of web browsers and I've also added V8 to my most recent C++ project. The only major drawback in my opinion is, that it's not statically typed.

I just tell myself it's because the sales pitch is so appealing: learn, and use, one programming language on the front end and back end of your web site. I've never written anything on node.js, but that's the only argument that's ever given me pause.
To me, the fact that Node has to add a library with custom semantics just to allow a basic 'open' on a file handle is a huge warning flag to me.
Earlier quoted context omitted.
Javascript as a language and ecosystem has evolved quite dramatically during the last years. Its not perfect though: it lacks features and ecosystem is still not in the level of maturity of other platforms, but is definitely going in the right direction. Regarding the single threaded server, its an architecture used before JS exists, and used by many other platforms/systems. Just to give you an example, Nginx workers…
In Nginx you're not doing computation, just passing IO thru between file system, external processes (i.e. PHP via fpm) and the network. If Nginx ever is CPU bound there's something bad happening. As I mentioned PHP: In PHP each worker is single threaded, too, but you can scale by having more workers in isolation.

I sometimes think we could do with a bit more thanking-our-lucky-stars that the language that got entrenched on the web wasn't, say, VBScript (which IE did use to support).
For your major drawback, there's TypeScript.
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…
Take away the web platform, would you still use JS for anything ?

You want to have fun programming, use Lisp. (Which, BTW, invented "arrow" fns ... aka Lambda functions!)

JS has the appeal that it's something a lot of people already have good amounts of experience with. And ES2015+ features add to the learning curve, but also give some much needed aid to existing problems; it's easy to pick up on async/await when you already know how promises work. 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 de…
I'm beginning to think npm has joke potential like regex. "I had a problem. I started using regex and now I have two problems." Becomes... "I had a problem. I ran npm install and now I have 21,735 problems."
Think about that for a moment: one library, 40 versions downloaded and compiled to fill NPM dependencies. What if there was a vulnerability in a version of that library - how do I audit that? Can I even fix it myself without hosting my own NPM registry? Bandwidth? Computation costs (a thing again, with cloud computing)? Disk space costs?
It makes me glad we just use Docker; so I don't have to try and make sense of the NPM madness from day-to-day. Just Docker's own brand of madness.
