Kotlin is an open-source, statically-typed language primarily developed by JetBrains programmers based in Saint Petersburg, Russia. Statically typed programming language means Kotlin performs type checking at compile-time as opposed to run-time.

Java was once among the most popular, most favourite programming language, however, looking at the limitations and errors caused by Java, developers required a desperate rescue. That’s when the JetBrains developers created Kotlin which proved to be much more efficient than Java. Kotlin has advanced benefits in terms of reliability, efficiency, runtime performance and maintenance when compared to Java, yet fully interoperable with Java, provides seamless integration with Java frameworks and libraries, and support backward compatibility. Kotlin also boasts about the fact that fewer lines of code are required to solve a problem resulting in clean, concise, easy to write and understand the code. Kotlin is developed just recently and is already gaining popularity among developers. Kotlin is becoming a strong competition to Java. The common issues that are a cause of frustration to Java developers are well covered in this young rival.

In May 2017, Kotlin was named as the official language of Android by Google. The team just decided to name it after an island and that’s why the name Kotlin (from Kotlin Island, near St. Petersburg).

Stack Overflow says that Kotlin is becoming developer’s favourite programming language and is outranking languages like Python and JavaScript. According to some survey reports, around 80% of Kotlin developers are using Kotlin as a programming language, around 30% use it for Backend/server-side applications and another 30% use it for SDK/libraries.

Coursera, Atlassian, Basecamp, Pinterest, Keepsafe are already using Kotlin in their mobile applications.

 

What makes Kotlin the fast growing language?

  1. Concise – This is the biggest advantage of Kotlin over other programming languages that you can solve the same kind of problem using fewer lines of code with a reduced number of bugs and crashes. Also, it makes the code more readable, easy to make changes and to maintain.
  2. Safe – Kotlin helps developers write robust and stable code. Kotlin’s smarter and safer compiler detect errors at compile itself and perform lots of compile-time checks reducing runtime errors.
  3. Interoperable – Kotlin is fully interoperable with Java. The existing codebase can interact with Kotlin and all existing libraries in Android can be used in Kotlin as well.
  4. Better Productivity – As it requires lesser lines of code, results in better productivity.

There are other lots of features in Kotlin that will speed up the daily development tasks.

Kotlin has undoubtedly won the heart of developers and has become a highly competing programming language. As it is open source and bring all advantages of a modern programming language into the Android platform, it is a great fit for Android developers. Migrating to Kotlin will really be a piece of cake for them. With all the cool features of functional programming, Kotlin is only getting brighter and better in Android community, however, only time can tell whether the popularity achieved by Kotlin in Android community can be achieved in other communities.
