Kotlin has now reached version 1.2, a “major release” that adds some interesting new features and curious wrinkles. After reaching its dot-zero (version 1.0) milestone, Kotlin was quickly adopted
as an official Android language. The most recent Android Studio release
supports it directly, and it has rocketed up various language trend lists
. Test allows you to write once and run your code under JVM and JS. HTML supports isomorphic rendering, which uses the same code to render HTML content on the back and front ends. Serialization uses JSON or ProtoBuf to “marshal Kotlin objects between different tiers of your application.” Boilerplate functionality has also improved. Kotlin 1.2 compiles 25 percent faster than version 1.1, and uses a more concise syntax for passing multiple arguments to array literals. Kotlin even has a new
library because – well, math.
Parsing the news a bit, we have to wonder if Kotlin is coming for iOS. Google has cloned Swift to serve as a “staging ground” for pull requests and the like, with Swift founder (and current Googler) Chris Lattner
saying there are lots of people working on the language in Mountain View. Between that and the Kotlin team's cagey language surrounding platform and language interoperability, Kotlin could be poising to become the next React Native.
