Kotlin: The Ultimate Guide

Kotlin is a free and open-source general-purpose programming language that is mostly used to create Android apps. It was developed by JetBrains initially and later on picked up by Google as language of chioice for its Android platform. Over the past few years, Kotlin has become one of the most popular programming languages over Java Language and is used by more than 80% of Android apps developers.

Kotlin is a statically typed, advanced programming language that compiles Kotlin code into Java byte-code and runs on a Java Virtual Machine (JVM). It can also be compiled to native executables and JavaScript source code. It is an object-oriented programming language that includes data types, operators, I/O comments, control statements, functions, classes, object expressions, and constructors, among other features. It is not a standalone programming language; rather, is an innovative manner of coding that runs on Java.

Kotlin is a versatile language with some interesting and cool features like compatibility, low runtime, and efficient coding characteristics. The features that help Kotlin distinguish out from other languages are its reliability, tool support, and interoperability. It is a simplified version of Java that is much easier to deal with.
