Kotlin is a programming language. It can be used to develop modern multi-platform applications for Desktop, Android, Web, etc. Kotlin runs on Java Virtual Machine like other programming languages: Scala, Groovy, Kawa, etc. It is relativly a new statically –typed langaue by 2017.It is targeted to runs on JVM and can be used anywhere Java is used today.

Advantages of Kotlin language

  • Easy to learn – Basic is almost similar to java. If anybody worked in java then easily understand in no time.
  • Kotlin is based on JVM and it is a functional language. Thus, it reduce lots of boiler plate code used in other programming languages.
  • Better performance and small runtime.
  • Kotlin is multi-platform – Kotlin is supported by all IDEs of java so you can write your program and execute them on any machine which supports JVM.
  • It’s much safer than Java.
  • Kotlin is a brand new language that gives developers a fresh start. It is not a replacement of Java, though it is developed over JVM. It is accepted as the first official language of android development. Kotlin can be defined as - Kotlin = JAVA + extra updated new features.
  • It allows using the Java frameworks and libraries in your new Kotlin projects by using advanced frameworks without any need to change the whole project in Java.
  • Kotlin programming language, including the compiler, libraries and all the tooling is completely free and open source
  • Kotlin is mature enough to build an interoperable application in a less complex manner.

Why Kotlin has become popular

If the word Kotlin has been buzzing around for quite some time, all the credit goes to Google Android, because Google had brought this language to lime light. Once Google Android declared that Kotlin will be one of the officially supported language for Android App development, Kotlin’s popularity had surged. And Kotlin has become popular with the existing Android community and also the emerging.

Why use Kotlin for Android Development?

  • Concise: Drastically reduce the amount of boilerplate code you need to write.
  • Safe: Avoid entire classes of errors such as null pointer exceptions.
  • Interoperable: Leverage existing frameworks and libraries of the JVM with 100% Java Interoperability.

Features of Kotlin

  • Kotlin reduces writing the extra codes. This makes Kotlin more concise.
  • Kotlin is null safety language.
  • Kotlin easily calls the Java code in a natural way as well as Kotlin code can be used by Java.
  • It explicitly typecasts the immutable values and inserts the value in its safe cast automatically.
  • It has better performance and fast compilation time.
  • Kotlin programs are build using the command line as well as any of Java IDE.
  • Kotlin supports extension functions and extension properties which means it helps to extend the functionality of classes without touching their code.
