Kotlin Introduction


Kotlin is a general-purpose, open-source programming language. It can be used to develop android apps, server-side apps and much more. It is a high level strongly, statically typed language and its code is more concise, readable and easy to understand. Its popularity has grown day by day.


The kotlin code runs on the JVM and its syntax is much like Java, it first compiles the code into byte code and then runs on the JVM as similar to the Java language. We can use any Java IDE for kotlin development.

In 2017, android team announced Kotlin as an official language for Android app development. After this announcement a large number of android users began adopting it.
