Kotlin

Kotlin is a modern, statically typed programming language designed for seamless interoperability with Java, making it a popular choice for Android development. Developed by JetBrains, Kotlin emphasizes conciseness, safety, and readability, helping developers write cleaner and less error-prone code. It supports both object-oriented and functional programming paradigms, offering flexibility for various coding styles.

Key features include null safety, extension functions, and a robust type inference system, which reduce boilerplate code and runtime errors. Kotlin can be used for server-side, web, desktop, and even multi-platform development, thanks to Kotlin Multiplatform.

Its compatibility with Java allows developers to call Java code from Kotlin and vice versa, making it easy to integrate into existing projects. Officially supported by Google for Android, Kotlin has rapidly gained a thriving community, solidifying its position as a versatile and future-proof language.
