        JS is Touring complete. You can write anything in it, including SkyNet or whatever else you can think of that will destroy the world.

          I want my world destroyed fast, thank you very much. Do you want them to stop mid-murder to prolong your pain because they’ve ran out of RAM?

          Say no to JS Skynet, embrace C++ Skynet!

        2 equal signs will coerce the second operand into the type of first operand then do a comparison of it can. so 1 == “1” is true. this leads to strange bugs.

        3 equal signs do not do implicit type conversion, cuts down on weird bugs. 1===“1” is false.

        edit: it appears to be more complicated than that for double equals and the position of operands don’t matter. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Equality

          Doesn’t it widen the types regardless of position? Meaning 1 == “1” will be compared as strings, not numbers.

              It seems it is that way, which is weird. You should always convert to the widest type, meaning string for comparing numbers and strings. I just checked that 1 == "01" is true, which means that “01” gets cast to an integer. And according to the document it might be that for example 1 == "a" would basically be interpreted as 1 === NaN which is false.

        Identity. “A is literally B” instead of “A equals B”. This is necessary here in JS because if A is the string “-1” and B is the integer -1, JS evaluates A==B as true because reasons

          because if A is the string “-1” and B is the integer -1, JS evaluates A==B as true because reasons

          Interesting. If it were the other way around, I think I would have been fine with it (i.e. == used for comparison with type like any other language and === without type). But as it stands now I would hate it if I had to write in JS (but I don’t so it’s fine).

            Honestly, I think it actually makes some sense this way around. To me, in JS “==” is kinda “is like” while “===” is “is exactly”. Or, put another way, “equals” versus idk, “more-equals”. I mean, “===” is a much stronger check of equivalence than normal “==”, so I think it deserves to be the one with the extra “=”

            It’s not that bad, honestly, just something you get used to. When I switch to C++ after a while, I sometimes write === and when I switch back to JS after some time, I occasionally forget to use ===.

            In C++ it’s obviously an error and for JS I have my IDE set to warn me about ==. I think I’ve used == in JS (and PHP) intentionally once in the last ~5 years.

      I use it regularly (web dev). A lot of complaints and mockery stems from using it badly. None of the programming languages that are regularly the butt of everyone’s jokes force you to use them badly, they just allow you to. If you follow good practices, you’ll be just fine.

        Many of the programming languages that are regularly the butt of everyone’s jokes don’t just allow you to use them badly, they make it easy to do so, sometimes easier than using them well.
        This is not a good thing. A good language should

        • be well suited to the task at hand
        • be easy to use correctly
        • be hard to use incorrectly

        The reality is that the average software developer barely knows best practices, much less how to apply them effectively.
        This fact, combined with languages that make it easy to shoot yourself in the foot leads to lots of bad code in the wild.

        Tangentially related rant

        We should attack this problem from both directions: improve developers but also improve languages.
        Sometimes that means replacing them with new languages that are designed on top of years of knowledge that we didn’t have when these old languages were being designed.

        There seems to be a certain cynicism (especially from some more senior developers) about new languages.
        I’ve heard stuff like: every other day a new programming language is invented, it’s all just a fad, they add nothing new, all the existing languages could already do all the things the new ones can, etc.
        To me this misses the point. New languages have the advantage of years of knowledge accrued in the industry along with general technological advancements, allowing them to be safer, more ergonomic, and more efficient.
        Sure, we can also improve existing languages (and should, and do) but often times for one reason or another (backwards compatibility, implementation effort, the wider technological ecosystem, dogma, politics, etc.) old quirks and deficiencies stay.

        Even for experienced developers who know how to use their language of choice well, there can be unnecessary cognitive burden caused by poor language design. The more your language helps you automatically avoid mistakes, the more you can focus on actually developing software.

        We should embrace new languages when they lead to more good code and less bad code.

    If you’ve seen the Barbie movie, there’s a scene where America Ferrera rants about the paradoxes in the expectations on women. The whole “be strong but not pushy” thing.

    That’s CSS.

            It’s not a debate I care to have, I just think it’s funny that people want to build websites but hate how websites are built.

            Fluent polymorphism via duck typing. It’s useful when you’re treating objects as a collection of properties, and therefore it’s not their type that matters but which properties they have. Types can still be used to label common collections of properties but it’s less painful to talk about objects that are “like an X but with/without certain properties,” or where some properties themselves have a different shape, etc. This is applicable to web APIs, not just because of JSON, but because it allows to define both very rigid and very flexible schemas without much overhead or repetition. See the OpenAPI specification.

      CSS is used to create the design, basically the look (colors, layout and so on), but no substance.
      JavaScript is used to implement code and logic.

      HTML + JavaScript would typically (since you’re supposed to use CSS to create colors and design) look very dull, thus the black-and-white Oppenheimer.

        document.querySelector('.whatever').style.color = "red";

        Don’t recommend, though.

          Sure, but setting the .style attribute could really be argued as using CSS, just with a different interface. W3Schools refers to this as “inline CSS”.

          Around flexbox is when I stopped caring about CSS, so it’s the last one I know. Is the grid better?

            They’re both tremendously useful and have significant overlap in use cases. Grid isn’t going to replace Flexbox, it just has some capabilities that aren’t part of the Flexbox concept.

            for some stuff absolutely, styling frameworks like bootstrap and others kludged together the concept of grid based designs. css grid just makes it official and more flexible.
