Depends on the criteria and the group of companies you survey. In our customer survey done mostly among top 100 enterprises it comes at #3 very close to Python (which is #2), and it is much stronger in absolute numbers than C# or JS. And th

I didn't say you got benefits of JS GC nor lack of JS GC. And that's the point: you don't get benefits, but you pay the price in lower productivity. Rust is a pleasant language to write in, but it is nowhere as expressive and

While Rust is a very cool technology, I don't think it is the best tool for web development. Manual memory management and constant thinking about ownership and memory sharing is additional productivity overhead, and you don't gain

I could easily find 11 collection types in Java as well. Any industrial language will have many data structures, because they have different tradeoffs and there is no single container that suits all needs. Scala standard library is a bit in

Same is true for any other mainstream language like Java, C# or Python. There are many ways to do the same thing, and this is why teams have code style guides and code reviews.

But Kotlin doesn't have 100% interoperability! There are features in Kotlin which don't map nicely to Java features. For example you can't call methods with default arguments from Java without resorting to unreadable hacks re

To some degree, yes. They allow to write software much faster, but in order to be truly proficient, you need to know a lot of what's in the layers below anyway. And when writing in a high level language, there are many more layers belo

My experience tells me the opposite. Scala codebases written by professionals are very readable even to people not knowing Java, but Python. Many analysts use Scala and Python. The only people I met who complained on Scala complexity were g

It is only because you are familiar with Java. Scala is much different language so it looks unfamiliar to you. But familiarity is not objective simplicity. Java has many more gotchas and irregularities than Scala, and you just got used to

Companions are in Kotlin too. Apply and unapply - I never saw this being a problem even for some new programmers switching from Python. Implicits are kinda harder to use, but this is an advanced feature meant for library writers, not applic

No they aren't contradictory. What is the compatibility of a feature that even doesn't exist in Kotlin? How can be the lack of way to call a Scala macro from Java a disadvantage, when Kotlin doesn't allow you to call a macro

You're missing the fact that the constant factor differs between languages. The density (bugs per LOC) of memory handling bugs is much different in Rust than in C.

Once you learn the Scala way of e.g. parsing JSON or defining any custom parser or working with collections/optionals you don't want to look back. I had to move back to coding in pure Java for a while after coding Scala many years

Scala compatibility with JVM is the same as Kotlin's. It is implemented the same way in both languages - they compile to JVM bytecode and as long as you keep away from non-Java features, interoperability is good both ways. If you start

Kotlin is less orthogonal than Scala. For example nullability in Kotlin is a special language feature that can't be abstracted nicely, when in Scala it works just as any other monad. Also I don't agree it is like Rust or Closure.

Scala doesn't have a ternary operator as well.

My limited experience with bare metal programming tells me they are not. This is just a different abstraction layer to learn. Often low level abstractions are much simpler and less broken than high level programming. Even if something goes

I don't know why you're downvoted, because I find your comment funny. Reminds me of a similar real fix for a race condition I found somewhere in one of the companies I worked before: Thread.sleep(Random.nextInt(1000));

All other things being equal, megapixels do count. DSLRs have both better quality in terms of dynamic range and noise AND more MP. More MP means more details, less grainy, nicer noise patterns, more cropping flexibility. 12 MP is good for i

Some IDEs show type hints on hover, or if type mismatch is detected, they display inferred types inline in code. E.g Intellij Idea does that for Scala and it is really useful. I wish it did that in Java as well.

Even in this case, after a failure of one engine, the other engine(s) are set to a higher thrust, which increases likelihood of their failure.
