An In-Depth Guide to Kotlin
Kotlin is a modern, statically-typed programming language that runs on the Java Virtual Machine (JVM) and can also be compiled to JavaScript or native code. Developed by JetBrains, the company behind popular integrated development environments (IDEs) like IntelliJ IDEA, Kotlin is designed to be a concise, safe, pragmatic, and interoperable language. It aims to address some of the perceived shortcomings of Java while maintaining full compatibility with existing Java codebases. This allows developers to gradually introduce Kotlin into their projects or use it alongside Java seamlessly.
