Meanwhile PHP quietly runs 80% of the internet by being used for WordPress.

Don’t tell my bosses that. Or the PHP community as a whole for that matter. Then I might have to get a real job.

The year they both came out (1995) I was coding in Visual Basic 3. Ack.

It will be 8 hours old forever.

Last company I worked at used Typescript, but used any for everything… I have no idea why. I never got an actual answer.

He also showed that JavaScript has more resemblance to functional programming languages rather than object oriented ones. If you try to treat it as an object oriented language like Java (like the seem to imply), you will have a bad time.

This has changed with TypeScript though.

I love how after a decade pandoc is still Haskell’s “killer app”. smh

Fortran would like a word.

I agree that the slow compile times are pretty bad (maybe even deal-breakingly for large projects). I think it’s kind of necessary for a language with as powerful of a syntax as Scala though, it’s pretty absurd how expressive you can get. Maybe if it didn’t target the JVM, it’d be able to achieve way faster compile times – I don’t really see a point of even targeting JVM other than for library access (not to say that that isn’t a huge benefit), especially when it has relatively poor compatibility with other JVM languages and it’s nearly impossible to use for Android (don’t try this at home).

Even more so, I think that null handling isn’t nice – I wish it were more similar to Kotlin’s. One thing I’m really confused as to why Scala didn’t go all-in on is Either/Result like in Rust. Types like that exist, but Scala seems to mostly just encourages you to use exceptions for error propogation/handling rather than returning a Monad.

A more minor grudge I have is just the high-level primitive types in general – it’s pretty annoying not being able to specify unsigned integers or certain byte-width types by default, but if it really is an issue than it can be worked around. Also things like mutable pointers/references – I don’t actually know if you can do those in Scala… I’ve had many situations where it’d be useful to have such a thing. But that’s mostly because I was probably using Scala for things it’s not as cut out to do.

With the tuple arguments point, I get it but I haven’t found it much of an issue. I do wish it wasn’t that way and it consistently distinguished between a tuple and an argument list though, either that or make functions take arguments without tuples like in other functional languages or CLI languages (but that’d probably screw a lot of stuff up and make compile times even LONGER). I saw someone on r/ProgrammingLanguages a while back express how their language used commas/delimiters without any brackets to express an argument list.

I think an actually “perfect” language to me would basically just be Rust but with a bunch of the features that Scala adds – of course the significant functional aspect that Scala has (and the clearly superior lambda syntax), but also the significantly more powerful traits and OOP/OOP-like polymorphism. Scala is the only language that I can say I don’t feel anxious liberally using inheritance in, in fact I use inheritance in it constantly and I enjoy it. Scala’s “enum”/variant inheritance pattern is like Rust enums, but on crack. Obviously, Rust would never get inheritance, but I’ve found myself in multiple situations where I’m thinking “damn, it’s annoying that I have to treat <X trait> and <Y trait> as almost completely serparate”. It would especially be nice in certain situations with const generic traits that are basically variants of each other.

Plus, I’ve always personally liked function overloading and default arguments and variadics/variadic generics and stuff, but the Rust community generally seems to be against the former 2. I just really hate there being a hundred functions, all a sea of underscores and adjectives, that are basically the same thing but take different numbers of arguments or slightly different arguments.

The custom operators are a double-edged sword, I love them and always use them, but at the same time it can be unclear as to what they do without digging into documentation. I guess Haskell has a similar problem though, but I don’t think Scala allows you to specify operator precedence like Haskell does and it just relies on the first character’s precedence. I would still want them though.

How it goes now, though, is I use Scala 3 for project design/prototyping, scripting, and less performance-sensitive projects, and Rust for pretty much everything else (and anything involving graphics or web). Scala has good linear algebra tooling, but honestly I’ll usually use C++ or Python for that most of the time because they have better tooling (and possibly better performance). I would say R too, but matplotlib has completely replaced it for literally everything regarding math for me.

They also thought the best thing to take from Python is that version 3 should not be backwards compatible with version 2

Ehhh, I mean this more strongly. I’ve never met people more in denial about language design problems than C++ adherents. (Though admittedly I haven’t spent much time talking to Lisp fans about language design.)

The thing it can do best is bewilder developers with it’s strange choices

but it can also do backend development

The same way a rusty spoon can dig a hole, sure.

That makes it versatile, not powerful.

When I hear powerful language, I think of languages that are good at intensive tasks like assembly, c, rust, Python (because of numpy, pandas, pyspark, cuda, etc.).

I exercised JavaScript out of some of my apps, and I’m happier for it.

if its acceptable to force javascript onto the backend and everywhere else, then why not write the frontend in rust, or anything else than can compile to wasm ?

JavaScript is AN UNAVOIDABLE HARDSHIP

I see where you’re coming from, but no matter how many null pointer exceptions there are in Java code, you’re almost always protected from actually wrecking your system in an unrecoverable way; usually the program will just crash, and even provide a relatively helpful error message. The JVM is effectively a safety net, albeit an imperfect one. Whereas in C++, the closest thing you have to a safety net, i.e. something to guarantee that invalid memory usage crashes your program rather than corrupting its own or another process’s memory, is segfaults, which are merely a nicety provided by common hardware, not required by the language or provided by the compiler. Even then, with modern compiler implementations, undefined behavior can cause an effectively unlimited amount of “bad stuff” even on hardware that supports segfaults.

Additionally, most languages with managed runtimes that existed when Java was introduced didn’t actually have a static type system. In particular, Perl was very popular, and its type system is…uh…well, let’s just say it gives JavaScript some serious competition.

That said, despite this grain of truth in the statement, I think the perception that Java is comparatively robust is primarily due to Java’s intense marketing (particularly in its early years), which strongly pushed the idea that Java is an “enterprise” language, whatever that means.
