It even has functionalities to facilitate interoperability with Java, like making easier to call Kotlin idiomatic code from Java. For example, you mention that it is compatible with Java lambdas, but that is more a merit of Java, rather than Scala. 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 … Consult our services page to learn more. As I’ve mentioned in the introduction, one of the main strengths of Kotlin is its perfect compatibility with Java code. For basic syntax, compilation & execution comparison refer to Java vs. Groovy, Scala, Kotlin – Basic Syntax Comparison of JVM Languages Features Summary. More or less you can do the same things with all of them. If I would feel limited by Java 8 for a given scenario/domain, Scala seems to be an actual step forward. You could argue that Kotlin has fulfilled its original objective: it became the first language to be officially supported for Android development, other than Java.

Any kotlin opinion will be biased as author did. Both Scala and Kotlin are statically typed languages which allows a whole class of compiler checks and static analysis tools. Working with an existing Java codebase? Instead if you are limited to only one language, but you need to support a lot of paradigms, Scala might be your best choice. Scala has the edge over Kotlin in some ways, but Kotlin is just as formidable in others. The design was based on the characteristics necessary to support software development at that particular time in history and based on considerations that made sense 20 years ago, less now. Calling itself “Java’s switch on steroids”, Scala’s match statement lets you match any type of data, including your own types. * Scala class can extend Java class and Java class can extend Scala class seamlessly Read interview with JetBrains CEO. Kotlin has the ability to compile down to JavaScript directly, and the Scala community has put together Scala.js. The other one, of course, was to create a better language than Java, but that was still compatible with the JVM. Well, we strived to be objective, but of course the fact we created a website named “SuperKotlin” is an indicator of where our preferencies lie We didn’t say that the language was academic, but that it was born in academia. However, I am not sure that there is one language that is definitely better for the web, just like there is not one language that is better for the desktop.

We can help with training, coaching and doing migrations for you. I have almost two years of scala expirience, I work with Spark in scala, I make websites in PlayFramwork and build distributed systems with AKKA, everthing in Scala. You can also use Scala for that purpose but it is not as hassle-free as Kotlin. You also aren’t forced to use more advanced features in the same way you are in C++. Most of the issues mentioned below stems from badly defined Java code, but they are all issues I have actually experienced in the wild. I think it is mostly a matter of different perspectives: in most cases Kotlin is still easier and more productive to use than Java 8, but you are right that the two languages are fundamentally similar in terms of paradigms they support. Functional programming is possible, but at a much easier level, making the learning curve a lot lower. Disclaimer: Scala developer here (also repost from reddit). 1) Scala is obviously compatible with Java to some degree, but only when it does not impede its main objective of being a great standalone language. We are going to update the article to reflect this. Interoperability with Java is not an accident, or simply what you can get by using a language that runs on the JVM. Is just my opinion.

So the potential is similar. Of corse some developers in some context will be much more happy with Scala, but I do not think it depends on who created the language. 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. Scala has its own area of application (big data and other cool stuff). There is vast difference in number of jobs being offered for Java programing, Scala programming and Kotlin programming. Many of these languages attempted to be a mix of improvements over Java and offering something more than Java. Scala is not an ‘academic’ language or ‘too hard to learn’. Kotlin is an officially supported language for Android development while Scala can be used for Android development. Like null checking. Project is currently in pre-release stage. “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. Scala isn’t a sandbox for professors. * Existent Java libraries can be easily used from sbt So they made Kotlin”. When comparing Scala vs Kotlin, the Slant community recommends Kotlin for most people.In the question“What is the best programming language to learn first?”Kotlin is ranked 7th while Scala is ranked 23rd. Kotlin quickly attracted many tech giants who encorporated Kotlin into their stack including Google, Square, Pinterest, and Atlassian. and Typesafe (now Lightbend) doesn’t want to make money? You are free to opt out any time or opt in for other cookies to get a better experience. As we said in the introduction we are not listing all the technical features, nor we are looking at the syntax. This has consequences for a variety of reasons. But which should be the next ruler of your code? As a conclusion, your article basically doesn’t rely on fact but your impression. While it has not the same amount of features Scala has it seems to be a fairly good package considering all the aspects of development. On the contrary it means that Kotlin designers think that Scala is a good language. 3. If you need Haskell plus Java, you should go with Scala. So to get the advantages of a smarter type systems you can only implement it with reference types. Considering this is coming from a Kotlin blog, this is fairly neutral however the thing that really stood out is point about null safety checking. It also offers full support for macros and higher-kinded types, making Scala ideal for big data processing tasks. It is not the right language for them. Scala vs Kotlin Antonio Leiva December 09, 2015 Programming 24 7k. Though Google’s support of Kotlin as an official language for Android significantly boosted its popularity, a newer community may mean less tutorials, tools and experts to lend a hand when needed.

But that doesn’t mean we shouldn’t find ways to improve upon it. But why would replacing Scala with Kotlin in the previous paragraph makes it somehow different? Click to enable/disable _ga - Google Analytics Cookie. Also, it shows full support for higher-end and macros types. Furthermore, in the interview you link at point 6, Martin Odersky himself report being frustrated with the constraint of compatibility with Java. This adds complexity and make Scala a famously hard language to learn and use. In fact Java is probably the most used programming language in the world. Because you can do so much with it, it is easier to do something sub-optimally, it is harder to find the good patterns and it is easy to have mismatching styles. Languages with design deficiencies will always appear ‘simpler’, but applications written in them will become more complicated. If you are an Android developer, learn Kotlin. Kotlin’s domain in contrast to Scala is mobile. Kotlin vs Scala: Which Problems Do They Solve? * Scala 2.12 requires Java 8 because compatibility with latest Java SE is important. We reported this fact and that is why you are going to see mentions about it in the comment. Scala also excels in the creation of complex internal DSLs, by including  macros and the chance of creating custom operators. 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.
