Just published a small experiment I’ve been mulling on for the past week or so: ember-simple-track-helper. It’s basically the same idea as React’s
useState hook, for Glimmer and Ember “template-only components” — places you don’t really need a backing class.
(As with all my recent packages, this is following the spec for SemVer for TypeScript I have been working on. So far it’s working well! Hopefully-final revisions to that RFC inbound in the weeks ahead!)
