I wouldn't say JavaScript is exotic, it's more to do with what is being done with it. Traditionally it was used to enhance HTML pages with some DOM manipulation but it's now being used for a million other things too. So historically, if your JavaScript code broke your page would still render as it was just html but now there are all sorts of build processes and long chains that use JavaScript to create the html in the first place... I'd consider that the exotic bit. Traditional JS running in the browser manipulating DOM elements is very much a foundational aspect of the web and won't deteriorate with age (with the exception of perhaps deprecated functions in the far-off future) but all these js libraries and tools and build processes with massive dependency-chains are what's being referred to.

It's been used as a general purpose programming language for over a decade. It is a 'boring technology' nowadays and hardly exotic. Of course, you could decide to do something exotic with it (edge rendering, data programming, whatever) but that's not a problem with the language but people wanting to stretch themselves...

  It still sucks by default. https://i.redd.it/h7nt4keyd7oy.jpg https://i.redd.it/h7nt4keyd7oy.jpg Yes, the ecosystem is pretty mature, we have things like ESlint, TypeScript, Babel, TC39, and so on.

JavaScript has matured massively over the past 10 years. I'm not a Node developer myself, but JS + TS is a very palatable combination to me. I'd pick it over many other languages. 10 years ago I would not have touched JS unless I was forced.

  Would you pick it for the back end as well as the front end?

  > I'd pick it over many other languages. I'd be interested to know which ones, because I can't think of one advantage that Javascript has - aside from the ubiquity of browsers. If we're comparing any other aspect of it though, I just don't know what advantage it has (seriously).

    Typescript has a pretty cool type system. A mixture of dynamic and static typing. You can be as dynamic as with js (or python), or stricter than Java (you can state a reference cannot be null for instance), or anything in between (and have dynamic parts and static parts in the same program).

      I haven't used Typescript but I've generally heard very good things about it. I didn't know you can mix and match, that might give me a bit more of kick to include it in a project, thanks. Whether or not it's an advantage of Javascript… I'm not sure. I mean, if someone wrote a transpiler for Java that overlayed stricter typing, would that really be an advantage of Java? Not sure, but of course, worth considering when choosing a language for a project.

    Functions are first class. Async i/o by default. Familiar syntax (I'm sure Haskell or Clojure are better languages, but they sure take some time to get used to. You can be fairly productive in js in very little time). There are packages for anything you can think of, no need to reinvent the wheel most of the times. And I even like it's single threaded nature. Being able to keep a process waiting without needing to spin a new thread with all that implies is very convenient. Edit: Original commenter had already mentioned typescript. So what's the deal with TS? I think on top of adding much needed type safety to Javascript, TS is also one of the best type systems you can ask for.

      Firstly, thank you for answering. I think most people would be too defensive (devs are a touchy lot:) to bother or just dismiss my sincere question. I'm going to disagree though (quite gently, I hope:) > Functions are first class. Always a good thing to have in a language but I struggle to think of a language that doesn't have this now. Java has it, C#, Python… if a language is being developed and didn't have it then now it does, right? Perhaps C doesn't - I checked, functions may be passed as arguments but does not allw nested functions, but it has callbacks so a type of closure is possible… hard to tell. Still, I'd say not using C was an advantage!:) > Async i/o by default I'm not sure which languages this gives an advantage over? > Familiar syntax I don't think this is an advantage, most languages are much of a muchness, and there are some serious footguns that still lay around in JS. Is `==` familiar? No, that's a footgun. Automatic semicolon insertion (ASI) rules? No, they're another footgun. Are fat arrow operators familiar? Doubtful. The new backticks? They're the other way round to what I'm used to. Certainly though, it can be picked up quickly enough. > There are packages for anything you can think of This is definitely an advantage over some newer languages, but over those in major use, it's not. Still, the way packages are installed and handled is… eye-opening. That wheel has been reinvented several times, and it still looks wonky. > I even like it's single threaded nature Sometimes that's a good thing, true, but it's not an advantage to have it set that way all the time. > TS is also one of the best type systems you can ask for I haven't used it, tbh, but I would say that an optional type system (it's optional in that you don't have to use TS, I don't know if it's optional once you start using TS, that would be better) is a definite advantage over some languages. It's not baked in though so that's half a point. I just don't see it. I think the driving force of the move to Javascript everywhere was because devs were tired of learning at least three languages (JS, something, SQL) and not being very good in all three (usually poor at SQL) and thinking they'd get more control by kicking out the DB guy who'd stop their bad ideas (because they didn't know SQL) and they could become an expert in one language to rule them all. Companies love it because of fungibility and more new devs tend to start with Javascript than anything else. Perhaps I've just got used to keeping several languages in my head?
