      https://medium.com/dailyjs/we-jumped-the-gun-moving-react-components-to-es2015-class-syntax-2b2bb6f35cb3 … 1: As much as it hurt, I'm happy Ember hung back on ES2015 class syntax.

      3: and have been working hard to land those features in JavaScript via TC39. Fields just made it to Stage 3. Decorators close behind.

      5: But as an Ember developer myself, I have appreciated the stability of a working, featureful object model while ES2015 classes fleshed out

      6: Not everyone remembers, but ES2015 intentionally shipped what we called "max-min" classes. We got consensus for what everyone knew

      7: was a too-limited feature set as an incremental step that we could build on in future versions. It saddened me at the time, but I knew

      8: Ember wouldn't be able to use ES2015 classes as-is. I gave my agreement for them and immediately got to work on the next steps.

          9/9: I'm enthusiastic about what we can build on top of a fleshed out class model, and happy (but exhausted) for having held out until now.

          I don't understand. class fields and decorators have been supported by Babel for ages - why can't Ember devs use them just like React devs?

          1: Nothing is stopping Ember devs. https://github.com/ember-decorators/ember-decorators … @rwjblue is on the core team. The core project is just more conservative

          2/2: about adopting features in-flux. Babel decorators and fields are a much earlier draft in ways that mattered.

          And again, I'm really just talking about how the communities reacted. Ember community took heat for hanging back but I think it was right.

          How have class fields changed in their path to stage 3?

          Some obvious ones: - they defineProperty instead of set (matters for setters on the proto) - x; produces undefined vs. a hole

          both of these can easily affect what happens when you subclass an object in pretty common ways.
