Kotlin is a statically typed programming language developed by JetBrains, designed to interoperate fully with Java. It is used for developing Android applications, server-side applications, and more, offering concise syntax, safety features, and enhanced performance.

About Kotlin
Kotlin was created by JetBrains in 2011 to address shortcomings in Java and provide a modern, expressive, and safe language for JVM-based development. It aimed to enhance productivity with concise syntax, null safety, and full Java interoperability.
Strengths of Kotlin include concise syntax, null safety, full Java interoperability, and strong support for Android development. Weaknesses include slower compilation times compared to Java and a smaller developer community. Competitors are Java, Swift (for iOS), and other JVM languages like Scala and Groovy.
