I will not show you every difference in syntax because it would take much more space than a blog article ever should, but I can explain the basic idea in simple cases. Developers of Kotlin tried to get rid of this disadvantage, and they did so very well. Eventually, you will need a significant amount of time to find what you are looking for in your code. JAVA is a really nice language, but as the project expands, the number of code lines increases logarithmically. Such code will be more transparent and easy to understand. When working with Kotlin, we can reduce the code by a lot of lines. The first argument which comes to my mind is Kotlin’s syntax. OK, that sounds good, but why is it better than JAVA? Another interesting fact is that you can compile Kotlin to JavaScript. You can use it to a code Back-end server, Andriod Apps or even iOS app using Kotlin Native. It is focused on interoperability, safety, clarity, and tooling support. For example, you can easily use JAVA libraries in Kotlin’s project, but Kotlin gives you more out of the box. What does that mean? Those languages can be used in parallel in the same project. Actually, to be honest, Kotlin is Java with some extra pieces of stuff. What does that mean? That is fully compatible with JAVA. It is designed for the JVM (Java Virtual Machine). Kotlin is object-oriented and supports functional programming features. You may say “IntelliJ is the best IDE for JAVA, those people know how to do the stuff, this Kotlin might be a really good tool” – and you are right! I mean, if you like JAVA and think it is a cool language then Kotlin is even cooler. Yep, the same guys who created IntelliJ IDEA. It is an open-source statically typed programming language designed by JetBrains. Yet this language is much more than that, Android being only a fraction of possibilities Kotlin offers. That is because Google decided that Kotlin was its preferred language for building Android apps. When you hear Kotlin, you will probably think about it as a programming language merely for developing mobile apps on Android, and you are right – but only partially. It is object-oriented and supports functional programming features. Kotlin is an open-source statically typed programming language designed by JetBrains.
