I still think the best solution to this is for the developer tools to curate a list of unhandled rejections. Just like `window.onerror` and the developer console work together to display unhandled exceptions, unhandled rejections could be treated very similarly. They would appear in the console while unhandled, then disappear when/if handled. (And there could be programmatic hooks too, just like window.onerror, e.g. `window.onunhandledrejection`/`window.onrejectionhandled`.) In case others weren't aware, the Promises/A+ group has been compiling ideas for the unhandled rejection problem at https://github.com/promises-aplus/unhandled-rejections-spec/issues?state=open _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
