  Introduction • The goalof this session is to equip you with insights that will allow you to make informed decisions about moving to Scala or Kotlin.
• 3.
  Why Moving BeyondJava? • Modern development demands more expressive, concise, and functional-capable languages. Java is robust but lacks many capabilities that developers find in modern languages such as Scala and Kotlin.
• 4.
  The Scala ProgrammingLanguage • Scala is a high-level, statically typed, multi-paradigm programming language designed to combine the best features of object-oriented and functional programming. • Scala was developed by Prof. Martin Odersky. The first version of Scala was released in 2003. • The code in Scala can be compiled into java byte code.

  The Kotlin ProgrammingLanguage • Kotlin is a modern, statically typed programming language developed by JetBrains. The first version was officially released in 2011. • Kotlin supports both object-oriented and functional programming paradigms. • Kotlin has gained popularity due to its ease of adoption for Java developers, making it an accessible yet powerful language for modern applications. • The code in Kotlin can be compiled into Java byte code.

  Scala and KotlinSimilarities • Both Scala and Kotlin are very similar. Moving from Scala to Kotlin or from Kotlin to Scala should be relatively simple. Both languages share the support for most of today’s modern languages’ capabilities, such as Pattern Matching, Primary Constructor, Extension Functions, Defining Objects, Properties, and Lambda Expressions.

  Scala and KotlinSimilarities • Scala and Kotlin allow us to integrate smoothly with systems already developed in Java. Whether we choose to develop a new project in Kotlin or Scala and use a Java library that was already developed or whether we choose to do the other way around, the integration is straightforward.
• 10.
  Scala and KotlinIDEs • I strongly recommend using the IntelliJ IDEA. The community-free version is sufficient. • The IntelliJ IDEA’s support, both for Kotlin and for Scala, is smooth and straightforward.

  Summary & Conclusions •Both Scala and Kotlin are very similar. Moving from Kotlin to Scala and from Scala to Kotlin is very simple. • Scala would most likely be the preferred option if support for big data is needed. If the support for Big Data isn’t a factor, it would most likely be better to move forward with Kotlin.
