Kotlin 1.2

Moving to Kotlin–the latest programming language to get official Android support. JetBrains announced Kotlin 1.2 and called it a major release which will let the devs reuse code between JVM and JS. The release announcement states that now one can write the business logic of an app once and reuse for the backend, browser frontend, and Android mobile app. So, this release supports multiplatform projects.

One should also note that IntelliJ IDEA 2017.3 (it’s being released this week) already comes bundled with Kotlin 1.2. In case you’re using Android Studio or older version of IntelliJ IDEA, you can get the update.

JetBrains says that they’ve been able to deliver about 25% performance improvement over Kotlin 1.1. In further 1.2.x updates, performance will be further improved.
