Bring simplicity to java development

• It's designed by web developers for web developers.• Type safety everywhere so you can have safe s…• Better testing capabilities• DI at compile time and runtime• Great ecosystem• Scheduling and asynchronous capabilities• Abstraction so it is easy to switch components• Asset compiler so you javascript is also typesafe• JSON is a first class citizen• Websockets, Comet, EventSource• Streams• So much to tell about him…• And once you join the club you can’t get out ;)
