This is how Google Inbox and Google Spreadsheets works. See the slides from my recently produced GWT Create Session (http://t.co/ZvoaHxCoZT). J2ObjC slide deck here (https://docs.google.com/presentation/d/1mW_Plm5jAygELf7qjVK7...) Videos of the conference will be online soon.

Prior to that, some 20% Googlers also produced the PlayN library (https://github.com/threerings/playn) This was taken over by Michael Bayne who added an iOS backend by Bytecode -> IKVM -> Mono conversion. I beleive j2objc and RoboVM backends exist now as well.

The major benefit of the j2objc approach is the avoidance of GC in favor of ARC, the conversion of message-sends into C-method calls when possible, and integration with existing iOS toolchain.

When we started, it seemed like an iffy idea, but after developing a product delivered to millions of users on a high volume site (gmail) that has 70% code sharing, and being able to simultaneously develop, test, and deploy across the platforms reasonably efficiently, a lot of skeptics have become converts to the concept.

We use Ionic as it is an awesome framework to build mobile hybrid apps with nativ access. Also Ionic has a nice community!

Cross-Platform goodness. I am a noob here...learning how to implement Ionic is on the top of my ToDo's

used on a recent project, an internal custom app developed for both ios and android.

Desarrollo de aplicaciones multi-plataforma con HTML5, JavaScript y CSS3

We have plans to employ this frontend framework in future apps.

Haaaaa. Really bad memories. We use react now.
