Introduction

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 its standard library depends on the Java Class Library.

Kotlin is officially supported by Google for mobile development on Android.

Kotlin was influenced by languages such as C# and Java. It first appeared in 2011, but however has only been Google's preferred laguage for Android app development since May 2019.

Features

Kotlin has many features such as:

Open Source
Full Java Interoperability
Kotlin compiles to JVM bytecode or JS
Data Classes in Kotlin
Defaulted Parameters
Kotlin imposes no runtime overhead
Null Safety in Kotlin
Extension Functions
Swift is like Kotlin
Kotlin wants you to write less code

Pros/Cons

Kotlin has its pros and cons:

Pros	Cons
Kotlin has received a lot of attention from the Android community and the bonus point is that it can also be used in the backend development like Spring 5.	The learning takes increased time as the language is comparatively ew and challenging and also the language has a concise Syntax.
Compared to Java, Kotlin is way more concise and hence the chances of errors are probably low.	The compilation of Kotlin is extremely slow compared to Java
Developers are privileged to make use of the Anko Library and currently, there are over 2000 Kotlin projects on Github.	The developer community for Kotlin is really small and also the answers to all the queries are not available on the ground of the language is new.
If you intend to make the switch from Java to Kotlin then it is easy. THe process is short and sweet, Install Kotlin Plugin, add the Plugin to the Gradle build files, and the select convert. You are done. It's this simple and easy.	The compilation and auto-complete of the Android Studio runs very slowly compared with the apps developed with the apps developed with pure Java.
The developers can now build cleaner APIs by including the smart extension functions.	The experienced Kotlin developers are very rare and hence be extra careful while choosing tutors. Finding the right expert can be really tricky.

Summary

In conclusion:

Kotlin, even though it isn't exactly a new language, is a fast growing language due to the fact it is going to become the only programming language used to make Android Apps, this makes it vastly important to learn and to develop new apps with. If you are a app developer or interested in app development, learning this language is a high priority.
