Generally speaking J2CL seeks to support Java language features and in the process of doing so make use of modern ES6 features. When it comes to the separate topic of making advanced ES6 features (that don't exist in the Java language) available to J2CL users the path for that is via the JsInterop spec.
To be specific: - J2CL currently outputs Closure goog.module()s instead of ES6 modules because no browser yet supports ES6 modules and we like having our output immediately runnable in the browser without a ES6to5 downsampling. When browsers support ES6 modules we are likely to switch. - When/if the Java language provides Decorators/Generators/Async functions we will transpile them - The JsInterop spec does not currently provide sugar for Decorators/Generators/Async functions but it might in a future revision - You can already take advantage of Generators and Async functions (but probably not Decorators) by using JsInterop to expose a JS library to Java where that JS library exposes utility functions for Generators and Async functions On Fri, Nov 13, 2015 at 1:27 PM, Paul Stockley <pstockl...@gmail.com> wrote: > Do you plan on supporting these features in j2cl in the future? > > On Friday, November 13, 2015 at 4:23:21 PM UTC-5, Ray Cromwell wrote: >> >> >> You could probably support Modules via a GWT linker.
