  • The is operator is for identity, not equality. Your example is just using it weirdly in a way that most people wouldn’t do.

    The + operator is for numbers or strings, not arrays. Your example is just using it weirdly in a way that most people wouldn’t do.

    I’m not defending Javascript’s obviously terrible behaviour there. Just pointing out that Python has obviously terrible behaviours too. In both cases the solution is “don’t do that, and use static analysis to make sure you don’t do it accidentally”.

    Sometimes I meet junior developers who have only ever used javascript, and it’s like (to borrow another contentious nerd topic) like meeting someone who’s only ever played D&D talking about game design.

    Yeah I think you can generalise that to “have only ever used one language”. I would say Python and Javascript are pretty close on the “noob level”. By which I mean if you meet someone who has only ever written C++, Java, or Rust or whatever they’re going to be a class above someone who has only ever written Python or Javascript.


  • Why would you use the is operator like that?

    Why would you add two arrays like that?

    Do you not use containers when you deploy

    No because I am not using Python to make a web app. That’s not the only thing people write you know…

    JavaScript is so bad you’ve resorted to using a whole other language: Typescript

    Well yeah. Typescript isn’t really a new language. It’s just type annotations for JavaScript (except for enums; long story). But yes JavaScript is pretty bad without Typescript.

    But Typescript isn’t a cop-out like Docker is.

    But the language it’s built on top of it is extremely warty. Maybe we agree on that.

    Yeah definitely. You need to ban the warts but Typescript & ESLint do a pretty good job of that.

    I mean I would still much rather write Dart or Rust but if I had to pick between Typescript and Python there’s absolutely no way I’d pick Python (unless it was for AI).





  • I dunno if you’re being deliberately obtuse, but just in case you really did miss his point: the fact that type hints are optional (and not especially popular) means many libraries don’t have them. It’s much more painful to use a library without type hints because you lose all of their many benefits.

    This obviously isn’t a problem in languages that require static types (Go, Rust, Java, etc…) and it isn’t a problem with Typescript because static types are far more popular in JavaScript/Typescript land so it’s fairly rare to run into a library that doesn’t have them.

    And yeah you can just not use the library at all but that’s just ignoring the problem.
