TIL about the greek question mark

Tell me, can you tell the difference between these two characters?

    Every syntax highligher shows this and VSCode even has a special case for this, this is not a real issue.

      I just tried and it just turns into a proper semicolon and everything works. (Sublime Text).

      That might explain that:

      In Unicode, it is separately encoded as U+037E ; GREEK QUESTION MARK, but the similarity is so great that the code point is normalised to U+003B ; SEMICOLON, making the marks identical in practice.

      And just like Reddit you’re complaining about it for absolutely no reason. How about we try to be a bit more welcoming and a bit less gatekeepery.

      programming hello world is doing better than most people and I applaud and welcome beginners.

      I am little more than an amateur myself, entirely self taught, and yet I’m forever digging into various bits of code for my marketing job, because paying someone $400 to fix a recalcitrant css style in a week and a half is worse than just doing it myself.

      Who the hell tries putting Greek question marks in their code? Like, I get most compilers will show you what character each error starts at, but still.

    I get this warning in my IDE (VS Code) so I feel safe:

    The character U+037e “;” could be confused with the ASCII character U+003b “;”, which is more common in source code.

    Laughs in just removing all semicolons because it’s not necessary in JS.

        That’s what’s really irks me be about JS–you can do just about whatever but you’re not supposed to.

        It’s an imperative language, but best practices are to use it functionally.

        You can omit semicolons, but best practices are to use them.

        You can use sloppy equality, but best practices are to always use strict.

          JavaScript reminds me of an older brother who happens to be the most laid back stoner you could meet. “Like yea man, you should probably use semicolons, but I ain’t gonna narc”

          After switching to typescript with linting and prettier I simply hate writing vanilla JavaScript anymore. Some people complain about the extra project setup needed but I find that time pays for itself immediately.

            Extra project setup like pnpm add -D typescript && tsc --init? One thing that is kinda annoying is that you have to manage were will js files go.

          You need to remember that a lot of those best practices are to cover for the performance issues from misusing loosely typed variables.

          The JavaScript engine can compile clean, type-safe code down to be almost as fast as properly compiled code. When you use various features like the loose equals or various object mutations and the like, the engine cannot optimize it, leaving your code much, much slower.

              Yup! I love TypeScript, and I love the flexibility of JavaScript. With all of the type templates and generics and other black magic TypeScript has, it’s pretty easy to even support the crazy stuff like mixins and contextual parameters (if I’m not speaking too loosely while avoiding proper terms!).

              A lot of the crazy stuff won’t optimize, but at least it goes to show how it’s not really tying JavaScript’s hands even when requiring TS everywhere.

          Except that you should use Prettier for formatting instead of ESLint. That said, semicolons are useless noise

              It adds even more auto formatting rules so you can basically stop thinking about formatting entirely. I used to be opinionated about formatting but now I just go with whatever prettier does. It’s not always the best but it’s consistent and it’s a big chunk of my brain I can free up for things that matter. It also formats things safely so you don’t run into those weird edge cases where semicolons matter if you choose to turn them off.

                Aren’t some of the scenarios for needing a semicolon logical-domain problems and not syntax issues? I wouldn’t trust autoformatting to spot a logical problem, though I also hope no one is writing code that flippantly. (as if honest mistakes aren’t common enough!)

                  Maybe there’s some edge case but in my years of using prettier I haven’t encountered one once.

            Never used eslint. prettier is a must. semicolons are only needed to split some rare TS syntax lines.

        I wouldn’t do it without an auto formatter. With prettier it will catch potential no semi colon issues.

          You absolutely have to use prettier with JS. I don’t think there is auto adding missing semicolons in C/C++ though, it would be very useful.

        Yes, true. I also did setup so that any missing semicolon will be added, because I got sick of not inserting them sometimes and then some code was without them and some was. (Before I tested just leaving them all out, out of fun, so I got into the habit of just leaving them out regularly)

    Why did Unicode even allow these symbols even exist? What happened to using a single encoding for similar symbols like in CJK? Uriel must be rolling furiously in his grave rn

      Because the point of unicode is to accurately depict every sort of writing regardless of format, not to make a neat table of every unique glyph. Fonts may want to render the two differently or treat them differently. Same reason why there’s a difference between an em dash and a quotation line mark

      Same reason why unicode is full of random characters that only ever appear like thrice in some Russian coptic manuscript from the 3rd century - it’s about being able to depict something, not perceived usefulness

      Also excuse my ignorance, but who’s Uriel? Because right now I just have the mental image of a very upset archangel which I’m guessing is not what you’re referring to. I mean it could be - I’m pretty sure unicode would fall under his domain of literature
