  • That’s entirely fair for the usecase of a small script or plugin, or even a small website. I’d quickly get annoyed with Python if I had to use it for a larger project though.

    TypeScript breaks down when you need it for a codebase that’s longer than a few thousand lines of code. I use pure JavaScript in my personal website and it’s not that bad. At work where the frontend I work on has 20,000 lines of TypeScript not including the HTML files, it’s a massive headache.

    This is the case for literally all interpreted languages, and is an inherent part of them being interpreted.

    It’s actually the opposite. The idea of “types” is almost entirely made up by compilers and runtime environments (including interpreters). The only thing assembly instructions actually care about is how many bits a binary value has and whether or not it should be stored as a floating point, integer, or pointer (I’m oversimplifying here but the point still stands). Assembly instructions only care about the data in the registers (or an address in memory) that they operate on.

    There is no part of an interpreted language that requires it to not have any type-checking. In fact, many languages use runtime environments for better runtime type diagnostics (e.g. Java and C#) that couldn’t be enforced at runtime in a purely compiled language like C or C++. Purely compiled binaries are pretty much the only environments where automatic runtime type checking can’t be added without basically recreating a runtime environment in the binary (like what languages like go do). The only interpreter that can’t have type-checking is your physical CPU.

    If you meant that it is inherent to the language in that it was intended, you could make the case that for smaller-scale languages like bash, Lua, and some cases Python, that the dynamic typing makes it better. Working with large, complex frontends is not one of those cases. Even if this was an intentional feature of JavaScript, the existence of TypeScript at all proves it was a bad one.

    However, while I recognize that can happen, I’ve literally never come across it in my time working on Typescript. I’m not sure what third party libraries you’re relying on but the most popular OAuth libraries, ORMs, frontend component libraries, state management libraries, graphing libraries, etc. are all written in pure Typescript these days.

    This next example doesn’t directly return any, but is more ubiquitous than the admittedly niche libraries the code I work on depends on: Many HTTP request services in TypeScript will fill fields in as undefined if they’re missing, even if the typing shouldn’t allow for that because that type requirement doesn’t actually exist at runtime. Languages like Kotlin, C#, and Rust would all error because the deserialization failed when something that shouldn’t be considered nullable had an empty value. Java might also have options for this depending on the serialization library used.


  • As a TypeScript dev, TypeScript is not pleasant to work with at all. I don’t love Java or C# but I’d take them any day of the week over anything JS-based. TypeScript provides the illusion of type safety without actually providing full type safety because of one random library whose functionality you depend on that returns and takes in any instead of using generic types. Unlike pretty much any other statically typed language, compiled TypeScript will do nothing to ensure typing at runtime, and won’t error at all if something else gets passed in until you try to use a method or field that it doesn’t have. It will just fail silently unless you add type checking to your functions/methods that are already annotated as taking in your desired types. Languages like Java and C# would throw an exception immediately when you try to cast the value, and languages like Rust and Go wouldn’t even compile unless you either handle the case or panic at that exact location. Pretty much the only language that handles this worse is Python (and maybe Lua? I don’t really know much about Lua though).

    TLDR; TypeScript in theory is very different from TypeScript in practice and that difference makes it very annoying to use.

    Bonus meme:


  • I haven’t checked back on it since I stopped using reddit (and I no longer use a surface pro) but there was a pretty active surface Linux community there as well with some good resources. For a lot of models you’ll need a USB keyboard/mouse to actually install the distro but once you can load the custom surface linux kernel things worked pretty well for me.



  • TypeScript is still built on JavaScript, all numbers are IEEE-754 doubles 🙃

    Edit: Actually I lied, there are BigInts which are arbitrarily precise integers but I don’t think there’s a way to make them unsigned. There also might be a byte-array object that stores uint8 values but I’m not completely sure if I’m remembering that correctly.





  • I’m a CS student and Linux was great for all of the programming classes. For any classes that were more writing focused you can still use the online versions of MS office/Google drive. I’m assuming there aren’t any programs you’ll need specific to psychology but that is sometimes a problem with some STEM majors like engineering

    The one problem that kept me dual-booting on my laptop was OneNote. I like taking notes using a pen for some classes (and my laptop has pen support) and nothing I tried on Linux even comes close in my experience. I tried obsidian + excalidraw plugin, along with xournalpp, but nothing came close for the way I take notes.


  • Technically I think python already has an intermediate step that it uses before it starts running a script that compiles it into a lower-ish language (at least the cpython interpreter does this, it probably isn’t a part of the language specification though)

    The actual line between JIT languages and interpreted languages is pretty thin since I think most interpreted languages do something similar to minimize the amount that needs to be done at runtime


  • Screw it. Let’s actually make python script an ISA that gets run on physical hardware with no higher level tooling. Then we can have the python virtual environment which runs this for fools who don’t have the right hardware. Finally, when people start complaining about naming we make Python Script 2.1, which is a JIT language built on top of IL that looks nothing like either of them but can emulate both python and python script with the performance cost of being a quarter as fast as both.
