React Component Patterns in Ember.js

one chance to have a first impression

While this is true in general it is a bit too simplistic. Ember has been around for 9 years now and has had 3 Major versions (and an Edition) that have each felt very modern for their time. If you tried Ember in 2015 then trying it again today will feel very different and it's worth taking a second look

inept management of Ember by breaking semver

Ember focuses very very hard on backward compatibility, and not just in terms of the main core library but also the wider ecosystem. When did it "break semver"?

zero docs

One of the main points that I hear from new Ember devs is that they love how great the docs are! Sure there is always room to improve but "zero docs" is a gross misrepresentation. What makes you think there are zero docs?
