I'll be waiting till async/await (ES7 maybe?) is available natively in browsers and node.js and its error handling story is cleaned up. Right now, in node.js if you're using streams2/3, it's quite the mess to recover gracefully already. Future of exception domains in node.js isn't clear to me either. Also, browsers aren't there yet either (eg. Fetch API error handling and aborting).
