Cover image for Advantages of Kotlin

Posted on • Updated on

Advantages of Kotlin

  • Easy to learn the basics.
  • Clean and Concise syntax.
  • Interoperable with Java(means each and every Java package/library/framework/API will work seamlessly with Kotlin), plus you know how much big the Java ecosystem is.
  • Provides nullable and type safety(means you don't need to write a whole try-catch block for catching null pointer exception because it can be handled safely, and casting is also much safer). Advantages of Kotlin
  • Strong type inference.
  • OOPS with added modern features.
  • Functional programming at its best, if we mix OOP+FP in Kotlin, we can even make very amazing DSLs.
  • Excellent and extended Java standard library.
  • Coroutines(and structured concurrency).
  • Wide range of apps can be made like mobile/android, desktop, full stack web apps and much more.
  • Also be compiled to JS and interop with JS to make frontend web apps, there are plans that Kotlin will even work seamless with Node JS in future.
  • Most Preferred language for Android development.
  • Kotlin Multi-platform Mobile(KMM) applications to make apps that will run natively on different platforms.
  • High speed UI development with Jetpack Compose(for Android) and Compose multi-platform(for Web and Desktop).
  • Can be used for data science/visualization, and deep/machine learning.
  • Kernel for Kotlin can be added in Jupyter notebook.
  • In Kotlin, even primitive types have their own classes, and you can even add your own methods to them using extension functions without doing any inheritance or making some classes.
  • Kotlin is open source and free to use, and there are many 3rd party libraries for Kotlin.
  • Kotlin can be added in any Java IDE(although IntelliJ IDEA is most preferred for Kotlin).
  • Kotlin can be easily integrated and work with any existing Java ecosystem or project.
  • Kotlin can interop with C and Obj-C for iOS and other developments, and Kotlin can be compiled to native binaries using LLVM, also WebAssembly support will soon be added in Kotlin.
  • Kotlin-Native and KMM plugin is available in Xcode IDE for making iOS apps using Kotlin.
  • Kotlin Coroutines are lightweight than Java threads.
  • Kotlin Coroutines are multi-platform, means they can be used when you are targeting JVM/JS/Native using Kotlin.
  • Kotlin can run as a script too(that eventually replaces the need of bash/groovy-gradle scripts).
  • Kotlin has a big, friendly and helpful community.
  • Kotlin is adopted by many major institutions and universities as a course in their academics.
  • Kotlin is also a suitable language for learning programming fundamentals and competitive programming.
  • Writing code in Kotlin might feel like it is a scripting language, but everything is statically typed.

Great post, Mohan! And welcome! Kotlin has been on my radar since even before its first release. This post was the first to sway me into actually trying it, tho, by answering quite a lot of the why-even-use-kotlin type questions… I’m super stoked about their plans for WASM and Node/JS support. 🙏
