Kotlin is a cross-platform, statically typed, general-purpose programming language with type inference. Kotlin is designed to interoperate fully with Java, and the JVM version of Kotlin's standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin is a programming language which is widely used by Android developers everywhere. 

Kolin is focused on interoperability, safety, clarity, and tooling support. Versions of Kotlin targeting JavaScript ES5.1 and native code (using LLVM) for a number of processors are in production as well. Kotlin originated at JetBrains, the company behind IntelliJ IDEA, in 2010, and has been open source since 2012.

About Kotlin Programming

• Open Source - The Kotlin compiler, Intellij IDEA plugin, and build tools are all open source.
• Interoperable - Kotlin is 100 percent interoperable with Java. This means all your current Java/Android code works seamlessly with Kotlin.
• Concise - Compared to Java, Kotlin code are much more concise. Also, Kotlin code is much more expressive (easier to understand and write).
• Tool-friendly - Kotlin is developed by JetBrains, the company renowned for creating development tools. You can choose any Java IDE to write Koltin code.

Why Learn Kotlin?

• Kotlin is 100 percent interoperable with Java. Hence your Java/Android code works with Kotlin.
• Kotlin allows you to cut off the lines of code by approximately 40% (compared to Java).
• Learning Kotlin is easy. It is particularly easy if you already know Java.
• Kotlin is tool-friendly. You can use any Java IDE or command line to run Kotlin.
