    From the README

    Welcome to Kotlin! Kotlin is a concise multiplatform language developed by JetBrains and contributors.

    Support for multiplatform programming is one of Kotlin’s key benefits. It reduces time spent writing and maintaining the same code for different platforms while retaining the flexibility and benefits of native programming.
