scala VS kotlin

I’ve been a web developer for years, but I haven’t touched Java in a long time — like, late-90s long. Back then, Java development felt cumbersome: lots of boilerplate and complex configurations. It was not exactly a pleasant experience for building simple web apps. So when I recently started exploring Scala and the Play Framework, I was curious more than anything. Has the Java developer experience gotten better? Is it actually something I’d want to use today?

Scala

Elm, ReScript, F#, Ocaml, Scala… it’s just normal to name your types, then use them places. In fact, you’ll often create the types _before_ the code, even if you’re not really practicing DDD (Domain Driven Design). Yes, you’ll do many after the fact when doing functions, or you start testing things and decide to change your design, and make new types. Either way, it’s just “the norm”. You then do the other norms like “name your function” and “name your variables”. I’m a bit confused why it’s only 2 out of 3 (variables and functions, not types) in this TypeScript Angular project. I’ll have to look at other internal Angular projects and see if it’s common there as well.

Scala is a programming language for the JVM born in 2004 that is both object oriented and functional. Since it runs in the JVM it can call any Java method and be called by any Java method. So, moving from Java to Scala is practically pain free, all you have to do is learn the new syntax. You have all the Java libraries at your disposal plus all the improvements Scala has to offer. Even though Scala is both OOP and Functional it doesn't force you to use either of the two paradigms and so it can just be used as a simple OOP replacement for Java with great benefits to speed of coding and readability. In this article I will not get into the details but just show you enough to make you curious and try it. If you want to dive deeper here is a link for you: https://www.scala-lang.org

Funnily enough this is (was?) used by the Scala collection library's TreeSet/TreeMap, for fast performance of the `take` and `drop` operations. This is a red-black tree though, not a B-Tree.

Recently I had to revisit the "JVM languages universe" again. Yes, language(s), plural! Java isn't the only language that uses the JVM. I previously used Scala, which is a JVM language, to use Apache Spark for Data Engineering workloads, but this is for another post 😉.

Next, I selected the technologies and frameworks I want to focus on during this challenge. For frontend development, I'll be exploring Reactjs, Vue.js, Bootstrap, Next.js, and MUI. For backend development, I'll be diving into Express, Django, Node.js, PHP, and Firebase. Additionally, I'll be learning Kotlin, React Native, and Flutter for mobile development, and APIs, PostgreSQL, Cloud, and MongoDB for full stack projects.

Kotlin

Kotlin, fully interoperable with Java, is increasingly used for Android app development. It offers a more concise syntax and improved safety features compared to Java, making it a modern language for mobile development. Discover more about Kotlin here.
