New kotlin book

Kotlin est un langage de programmation orienté objet et fonctionnel, avec un typage statique qui permet de compiler pour la Machine virtuelle Java et JavaScript. Son développement provient principalement d'une équipe de programmeurs chez JetBrains basée à Saint-Pétersbourg en Russie (son nom vient de l'île de Kotline, près de St. Pétersbourg).

Google annonce pendant la conférence Google I/O 2017 que Kotlin sera un des langages de programmation de base pour android.
Kotlin is a brilliantly designed, mature language that we believe will make Android development faster and more fun. It has already been adopted by several major developers — Expedia, Flipboard, Pinterest, Square, and others — for their production apps. Kotlin also plays well with the Java programming language; the effortless interoperation between the two languages has been a large part of Kotlin's appeal.
The Kotlin plug-in is now bundled with Android Studio 3.0 and is available for immediate download. Kotlin was developed by JetBrains, the same people who created IntelliJ, so it is not surprising that the IDE support for Kotlin is outstanding. In addition to the IDE support, we're announcing a collaboration with JetBrains to move Kotlin into a non-profit foundation. (Kotlin is already open sourced under Apache2.)
In case you are concerned about other platforms that Kotlin supports (Kotlin/JVM for server and desktop, Kotlin/JS and Kotlin/Native), please be sure that they are as important for us as ever. Our vision here is to make Kotlin a uniform tool for end-to-end development of various applications bridging multiple platforms with the same language. This includes full-stack web applications, Android and iOS clients, embedded/IoT and much more.

Programming languages are just like human ones: the more people speak a language, the better. First-class support on Android will likely bring more users to Kotlin, and we expect the community to grow significantly. This means more libraries and tools developed in/for Kotlin, more experience shared, more Kotlin job offerings, more learning materials published, and so on. We are excited to see the Kotlin ecosystem flourish!

We will be partnering with Google to create a non-profit foundation for Kotlin. Language development will continue to be sponsored by JetBrains, and the Kotlin team (over 40 people and second largest team at the company) will operate as usual. Andrey Breslav remains the Lead Language Designer, and Kotlin will be developed under the same principles as before. We’ll keep our design processes open, because your feedback is critical for us in moving Kotlin in the right direction.

If you’re at Google I/O, make sure you stop by one of the Kotlin talks on the schedule. And of course, don’t forget to register for KotlinConf in San Francisco in November. It will be an amazing event!
A Big Thank You!

When we started the journey with Kotlin over 6 years ago, we aimed at creating a language that would be in line with the same principles that drive our tools – create something that helps developers with the tedious and mundane tasks, allowing them to focus on what’s truly important. And of course make the process as enjoyable and fun as possible.

We want to thank Google and the Android team for their trust in Kotlin, but above all we want to thank you, our community, our users. Without you Kotlin wouldn’t be where it is today. Thank you for accompanying us during this journey and we hope you join us for the exciting road ahead.
