2010年，长达是十年之久的Java开发让JetBrains的工程师认为老旧的Java语言已经严重阻碍了生产力。他们认为是时候开发一款现代化的JVM语言了，这也是因为他们有足够的资源和专家。本身做各种IDEs起家的JetBrains就开始着手新工具的开发——一个编程语言。</p>    <p>     Kotlin可以通过versa调用Java方法，源码可在同一项目中混合使用，甚至生成的.class文件完全兼容Java工具。JetBrains内部现在已经有一个超过20个开发人员的团队使用Kotlin开发。 目前已经有大量的开发人员使用Kotlin开发web服务后端和Android应用。</p>    <h2>更新日志</h2>    <ul>     <li><a
