kotlin vs scala

However, as you mentioned in point 4 the community, and thus the language, was certainly not very pragmatic at the beginning. Kotlin vs. Scala. It is not the right language for them. Project is currently in pre-release stage. the most used programming language in the world, an interview with the lead Kotlin developer, enthusiasm with which Kotlin was received, a great online test environment with examples, http://www.artima.com/scalazine/articles/origins_of_scala.html, https://wiki.haskell.org/Haskell_in_industry, Developing web applications with Javalin and Kotlin, All the Talks at KotlinConf, Organized and Commented. Scala stands for Scalable Language, a language designed to scale with the needs of its users, while Kotlin is the name of an island, just like Java. So Kotlin brings some features that are already in Java 8, but are not available to Android developers. Easy to Learn. On the other hand, as you said, Kotlin and Groovy seems more similar. 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. For many the answer is Kotlin. Kotlin additions in many cases are what is usually called syntactic sugar. Many successful languages have precise objectives and a specific philosophy of what programming should be. 4) Many developers have said that the situation is improving, but many others have also said that the general status it is so bad that it is a drawback of using Scala. Or really almost any other modern language. Most of the people that had the first motivation are happy with Scala. A great merit of Scala is that it proved to be possible to build another major static language for the JVM. Java that is. I think it’s a bit provoking that this article makes the impression of doing a “objective” comparison, but then not giving any reason at all for learning or using Scala. Scala and Kotlin supports also other programming paradigms. Features in Scala have purpose, and it’s clear that they fit in the language. This means that … Instead if you are limited to only one language, but you need to support a lot of paradigms, Scala might be your best choice. Previously the official Scala website offer an Eclipse-based IDE. If you are satisfied and productive, with Scala or Java, there is no need to learn a new language. Kotlin is a statically typed programming language for the JVM, Android and the browser, 100% interoperable with Java What is Scala Native? Nevertheless it is important to  see some significant features and the approach the languages pick. As we said in the introduction we are not listing all the technical features, nor we are looking at the syntax. Java is also arguably the most used language in the enterprise world and the most widely taught language in computer science courses. They tried to bring the most value in the way that was easier to use. Scala is not an ‘academic’ language or ‘too hard to learn’. On the contrary it means that Kotlin designers think that Scala is a good language. On the other hand, Scala is detailed as " A pure-bred object-oriented language that runs on the JVM ". When looking at Kotlin, it does not try to do the same as Scala, but puts developers first. In fact Java is probably the most used programming language in the world. 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 … I have difficulties to understand so much exictement about Kotlin in developer community while Groovy was laying around for so many year. You say “but compatibility was not really a primary objective”. For instance, there was no good IDE, it was created by another company. As a conclusion, your article basically doesn’t rely on fact but your impression. It even has functionalities to facilitate interoperability with Java, like making easier to call Kotlin idiomatic code from Java. It is not a secret that many developers, and companies, want something more productive and I dare say fun to use. Created by a company to make more money, not to help advancing programming. Kotlin fixes Java’s bad parts and keeps its good parts. 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. And many developers are happy with Java. Scala vs Kotlin Antonio Leiva December 09, 2015 Programming 24 7k. This is quite an interesting comment. I used the language the first time a couple of months ago. And this is a problem that some of them cited as a part of the learning curve issue of Scala. While it is growing quickly, the Kotlin community still has some catching up to do with Scala. 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 But just like C, Java is old. This begs the question: is there anything wrong with Java? Even if you disagree with that specific example I don’t think it invalidate the general point. Not as great. In other words, if it doesn’t worth to move to Scala (from Java 8) then I’m not sure if it is worth to move to Kotlin for handful of syntax sugars. This does not necessarily mean than Kotlin is better than Scala, of course. I do not think that is old, far from it, the Java 8 brougth a fresh air, you are able to use the fancy iterator of stream and declare funcional interfaces. A more concise way to express common patterns used by developers. I think there is a very bad prejudice (stemming from poor education) against dynamic typing…. Java became closer to Scala, by implementing lambdas. Kotlin is compilation of (best) modern practices. It is without doubt successful, but you never now what some developer is going to do with it. And you definitely don’t need a Phd to use it. Scala for Big Data & Mixed Coding Paradigms. Click to enable/disable Google reCaptcha. Since Kotlin is younger than Scala, it has fewer libraries, blog posts, and tutorials. In Kotlin there’s simply less of it. For example, many developers lament the overuse of arcane custom operators whose purpose is not really clear from the code itself. Haters gonna hate, developers gonna ship the products. As always, the trick is in finding the right tool for the job – a language that is equally comfortable for you, and compatible with the goals of the project. A lot of the other discussion in that thread seems much more sincere and reasonable, and make good arguments. Kotlin will suffer the same fate of large monolithic java applications because it made so many of the same design flaws. We may request cookies to be set on your device. Maybe some of it is sarcastic jokes I don’t understand. * Existent Java libraries can be easily used from sbt And that is simply a fact, though of course we can argue about its meaning. Outside the Android world, Kotlin is still not as useful or applicable as Scala. Both Kotlin and Scala have many productivity features that are standard in new languages, but they were not so when Java was created, things like type inference and quick ways to create a singleton or a data class. The relative lack of native libraries is somewhat mitigated by the excellent Java compatibility. Kotlin is also more powerful than Java. Another benefit is, that code written in Kotlin can work perfectly with your existing Java code. Many of these languages attempted to be a mix of improvements over Java and offering something more than Java. Click to enable/disable _gat_* - Google Analytics Cookie. People are just provoked by what they think is incorrect criticism. 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. Yes, you can. Difference Between kotlin and Scala. And although Java has evolved more than C, and luckily in a more organized way that C++, it is lagging behind many other languages. Click to enable/disable Google Analytics tracking. Scala has a larger community, if nothing else because it has been around longer. Some of these observations are truthful, at least in part, but even then I don’t think they invalidate all the comparison itself, which is about 3000 words in length and generally correct. So Java is great, just like C is great. Or more generally, a better language than Java. 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. Any kotlin opinion will be biased as author did. Was a feature really necessary or were there alternatives? As I’ve mentioned in the introduction, one of the main strengths of Kotlin is its perfect compatibility with Java code. 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. * smart-cast (known as flow-sensitive typing) Kotlin or Scala? I am sorry, but Kotlin is nowhere close to the level of Scala. 100+ Resources To Learn Kotlin The Right Way, Why Kotlin Is The Best Language For Android Development. With Google and JetBrains (who brought you Intellij IDE) supporting the Kotlin ecosystem, there are undeniable advantages. Slant.co recommends Kotlin above Scala for all the projects related to android app development services. It’s definitely a biased article from where it posted.

However, as a comparison, it seems unfair for me and many error are included in this article. It was designed with this goal in mind, and it has most features that you will find in Haskell, but not in Kotlin or Java, such as currying, memoization, partial application, type classes… It has the whole package, so to speak. Using Scala, you can avoid bugs in complex applications. We hope that this pragmatic comparison has been useful. Kotlin created by people with ambitions. Corda actually did just that: Excellent documentation and tiny standard library makes it a very fast language to learn. To deal with NPEs, Scala replaces null values with Option, which adds some complexity to the code as it needs to be explicitly used. The only question is which language benefits the most developers in different situations. That is because conciseness might be better when you are writing code, but it is worse when you are reading it. Even if a single developer would be willing to do no matter what to learn a certain language, that cost would keep many others out, limiting the number of libraries written in that language, the investments in tooling and hampering the development of the community. Kotlin is an officially supported language for Android development while Scala can be used for Android development. Which ultimately means in Scala its consistent, its pretty much always Option and no one really works with null where as Kotlin has to deal with the hodgepodge of putting effort to make null checking better (even though you couldn’t do it completely because its impossible to do so) and now having to deal with Java’s new Optional. It means that Scala was also designed to solve pragmatic problems. Smart casts means that if you check the type of a variable that is automatically cast to the new type, of course if it actually is a variable of that type. * sbt depends on maven ecosystem and can use easily maven artifact Because these cookies are strictly necessary to deliver the website, refuseing them will have impact how our site functions. independent (top-level) functions are fine and you do not need to make utility classes to contain disparate functions, Kotlin defines expressions rather than statements, so you can assign to variables things like the result of, you can easily define immutable data with. * Scala 2.12 requires Java 8 because compatibility with latest Java SE is important. While Kotlin offers some support for functional programming it really does it to accomplish easier procedural or imperative programming. If you are training a new developer in Scala you might also have to explain to them how they should use this or that feature of Scala. For many years developers have built new languages on the JVM. Kotlin wants to be a better Java, while Scala plans to be much more than Java. Whereas Kotlin is an enchancment over Scala in some methods, it lags behind the latter in others. We do not explicitly advertise our positions as needing Kotlin experience and have been hiring people who didn’t know it already, with ramp-up times in the range of 1-3 days before the new team member is producing idiomatic code. Scala vs Kotlin popularity in … While Kotlin ranks 11th, and Scala stands 17th amongst the best programming languages to learn first. Kotlin has a lot of interesting features but I think its creator found a balance between introducing new features and the cost they would have brought in terms of complexity.

About kotlin, for me, is just another JVM languague, I was very suprised when Android took it as primary languague, and do not understand the need of it, since that just want to be a replacment for Java and not a more than Java. When choosing a programming language, number of opportunities and payment scale should be a major criteria for any candidate. It doesn’t matter if you’re developing in Java, Scala or any other JVM languages, there’s always something new to learn about from other JVM languages. But considering that Kotlin improves on few fundamentals I’m not convinced it is a great benefit to move from Java 8 to Kotlin. But this will always prompt you to accept/refuse cookies when revisiting our site. While working at a Scala company a few years ago, I documented a few pitfalls regarding Scala / Java interoperability. With less code lines, there is less room for bugs and also makes the code written easier to read. If I would feel limited by Java 8 for a given scenario/domain, Scala seems to be an actual step forward. In fact, the  quote comes from an interview with the lead Kotlin developer that explained one of the reasons because they decided to create Kotlin.
