What is Kotlin used for?

The question is about kotlin

Answer

Kotlin is primarily used for Android app development due to its modern features and seamless integration with existing Java code. It offers advantages such as null safety, concise syntax, and improved performance, making it a preferred choice for developers. Beyond Android, Kotlin is also used for server-side applications, web development, and cross-platform mobile applications through Kotlin Multiplatform. This versatility allows developers to write clean, efficient code that can be shared across different platforms, reducing development time and effort while maintaining high-quality standards.
