I know their not long for this world, but class name bindings on components. That was such a delightful ergonomic coming from react/backbone

I love hearing that people still get value from original features that we've found ways to improve. Re: not long for this world, `...attributes` on Glimmer components should be even more ergonomic than classNameBindings, right?
-
I’ve only done a single spike on Glimmer.…attributes wasn’t an obvious solution at first pass. Should a chance to play with it again arises, I’ll give that a try
-
I'd love to hear about your experience if you give it a shot.
-
It’s been a while (the last I played was 5/03/17) but I think some observations are still relevant: 1. Components templates as outerHTML took a bit to readjust but it totally the right call 2. The same for args/props
-
Coming from ember, the boundaries between the two are really confusing. Like, I’m using the “same” cli but can’t generate services, etc. When you think about it’s obvious, but it’s takes some cycles.
-
As a general observation of the tool, it makes sense as a experimental playground, but not as a competitor to react/vue. I know very capable devs who chose Vue because react seemed like too much to them. Typescript plus the coupling of the cli strikes me as a mountain too high
-
That’s what I got for now. Hopefully some of it is what you were looking for.

Testing user interactions in Ember is awesome. I don't think the wider JS community knows how amazing the testing story is.
-
I agree that the testing story is absolute brilliant. Light years ahead of anything else I've seen.
-
I'm seeing so much love for the testing story. \o/ I also love https://github.com/emberjs/rfcs/pull/327 …, an effort to improve testing ergonomics and accessibility at the same time, based on
@jgwhite's amazing EmberConf talk. - 1 more reply

The addon ecosystem is definitely a killer feature. PWA is quite literally just 4 addon installs. I know that the core team doesn’t want to endorse certain addons, but I think there should be a cookbook style guide to help people get on the most recent buzzword feature.

I think that the Rust "libz blitz" approach was pretty darn good for "in the moment stdlib"https://blog.rust-lang.org/2017/05/05/libz-blitz.html …

I recently started working with React and last week we had to solve a problem about controlled and uncontrolled inputs. I guess it is a minor thing but I never had to think about something like that with Ember.
-
What's a controlled vs. uncontrolled input?
-
It is basically if you control the state of an input (e.g. the checked state of a checkbox) completely by yourself (through passing in the right properties) or if the dom element itself can handle it. I have no idea why this is necessary but it is really confusing.

As others have said, testing is an absolute pleasure. I’ve used tons of testing frameworks throughout my 15 year career and Ember’s is by far the best.

The thoughtful upgrade path isn’t a sexy feature but it has made such a tremendous difference for my team.

Best thing for me is the ****VEEERRRYY*** extended version compatibility of all addons in the ember ecosystem. Things from 1.13 work on 3.x Especially in JS world, nothing else works this way (unfortunately)
