kotlin vs scala

Nevertheless, I ran a very quick example: I compiled some Project Euler solutions in Kotlin and Scala. Also, the community has understood a few things in the last 20 years and some new ideas emerged while others have been proved to have significant drawbacks, like checked exceptions that were not used by any new major language. FMPOV, Scala use in Play framework to create web application. Kotlin is leading (primary soon) language for android development and “better java”. People are just provoked by what they think is incorrect criticism. Click to enable/disable essential site cookies. Kotlin vs. Scala: Which is Proper JVM for 2020?

You can check these in your browser security settings. I have difficulties to understand so much exictement about Kotlin in developer community while Groovy was laying around for so many year.

I can understand the merit to move from Java 6 to Kotlin for Android development. While Scala and Kotlin both run on the JVM, both languages are also pushing towards “native” support. * Scala class can extend Java class and Java class can extend Scala class seamlessly And although Java has evolved more than C, and luckily in a more organized way that C++, it is lagging behind many other languages. It is still certainly good enough for daily use. Scala created by people with dream. This means more resources, more tutorials, and more (useful) answers on StackOverflow and Reddit. Talk by Javi Pacheco and Antonio Leiva comparing both languages when developing Android Apps. Not as great. So Kotlin brings some features that are already in Java 8, but are not available to Android developers. Scala was designed to successfully marry functional and OOP paradigms, and it does so fairly well. I’ve never seen more aggressive community than Scala, it might be subjective. Your email address will not be published. Using Scala, you can avoid bugs in complex applications. Another benefit is, that code written in Kotlin can work perfectly with your existing Java code. This is not strictly a flaw of the language, you can do more, so there is more to learn. Yes, you can. For many the answer is Kotlin. Some (x) or maybe none of them. Any kotlin opinion will be biased as author did. It’s also weird to compare Scala to C++, which is a really scary Frankenstein monster by now. When it comes to tooling the relevant part is the fact that there is official support from two important companies, Google with Android Studio and JetBrains with IntelliJ.

Especially if you’re invested in their tech stack (Play, Akka). The article makes it sound like Scala is Haskell, which is kind of ridiculous. But robust libraries with idiomatic Kotlin code are not always available in Kotlin or they are not as deeply developed as the ones for Scala and Java. This site uses cookies. Much effort is put in to maintaining compatibility with Java. Calling itself “Java’s switch on steroids”, Scala’s match statement lets you match any type of data, including your own types. Not that there’s anything wrong with being old. So bottom line is – Kotlin is for stupid developers. The main differences — where the … Java became closer to Scala, by implementing lambdas. We need 2 cookies to store this setting. It’s definitely a biased article from where it posted. As famous from the aforementioned elements, Kotlin and Scala are considerably in a tug of battle. If you are a student or have time to learn something new, learn both. * Scala’s type system is designed to work with Java’s type system and Kotlin inherit Scala’s approach basically (generics, variance, type hierarchy, ‘no static’, etc.) All approaches have flaws. It does that with lambdas and the help of some syntactic sugar. Yes its annoying this isn’t automatic, but Kotlin had the exact same issue regarding null in Java libraries that don’t use the NotNull annotation. Haters gonna hate, developers gonna ship the products. One of the pain points of Java that Kotlin addresses is boilerplate code. While it is possible to achieve similar results with smart application of the when clause, Scala’s matching capabilities and ease of use are far ahead. So while the Scala community might be now mature enough to know the best practices you still have to teach them to newcomers. But this situation happens quite rarely. Null security: Scala gains a decision monad thus, which happens in secluded among two expressions. Scala instead has all you may want from a language that need to be both functional and object-oriented. For instance, individual functions can now be first class citizens of the language. * sbt depends on maven ecosystem and can use easily maven artifact Scala reminds me of C++: there is always place for one more feature. This gave me for a fresh re-compile of the whole project: 6 seconds in Kotlin (down to 5 seconds in successive re-builds) 10 seconds in Scala (down to 7 seconds in successive re … That is because conciseness might be better when you are writing code, but it is worse when you are reading it. Scala has the edge over Kotlin in some ways, but Kotlin is just as formidable in others. This is the curse of success: so many people use it that the designers cannot really change the fundamentals even if they had discovered they were wrong about something. Since Kotlin is younger than Scala, it has fewer libraries, blog posts, and tutorials. This is a quick table of summary of comparison. Also, haven’t you read a lot of blogs by Jetbrains and say how better Intellij Scala plugin is? Slant.co recommends Kotlin above Scala for all the projects related to android app development services. 5) That is technically correct and we talk about several powerful features of Kotlin. Scala was created to run on the JVM platform, for easier deployment, but compatibility was not really a primary objective. Probably the original developers find these concise operators a good thing, but some user find them obscure. https://superkotlin.com/wp-content/uploads/2017/06/Kotlin-vs-Scala_-Which-Problems-Do-They-Solve_.jpg, https://superkotlin.com/wp-content/uploads/2019/06/LOGO-SUPER-KOTLIN_300.png.

Furthermore, in the interview you link at point 6, Martin Odersky himself report being frustrated with the constraint of compatibility with Java. With features neither Java nor Kotlin possess (like pattern matching, macros, and higher-kinded types), and perfect compatibility with Apache Spark, Scala is the language for data science and complex mathematical modeling. As for the documentation, it is not really a case of Scala is bad, but Kotlin is awesome. Scala also excels in the creation of complex internal DSLs, by including  macros and the chance of creating custom operators. With Kotlin you can truly enjoy the greatness of JVM ecosystem that makes it the platform of choice for so many projects today. Is just my opinion. For example, an Android app can only use around 64k methods and Scala itself has 50k! “Scala has the right features, but its most obvious deficiency is very slow compilation.” These words were said by no other than the lead developer of Kotlin.

As a side note, I do consider JVM, the platform, to be much more valuable invention than Java, the language. Kotlin is easier to learn than Scala. This article compares Java vs. Groovy vs. Scala vs. Kotlin on the basis of several language features using code examples. Kotlin has the ability to compile down to JavaScript directly, and the Scala community has put together Scala.js. We are not bad mouthing Scala or saying it is a bad language. * smart-cast (known as flow-sensitive typing) It could work in some places, but I am not sold to the idea for everybody. This is useful to reduce the need for complex string interpolations. Before we discuss the use-cases and criteria upon which to select Kotlin or Scala for your next project, let’s get acquainted with the history, and the major strengths and weaknesses of each.
