Signals & fine grained reactivity in Angular
summary
Claims that Angular will make zone.js optional and adds a new primitive called signals to enable lazy computations, effects that subscribe by calling .get, and automatic unsubscribe via WeakRef. The demo uses an early PoC integrated into Angular, shows a push pipe and a structural let-like directive that call detectChanges on a single embedded view, reducing re-evaluation from the whole app to one component; experiments run live but remain experimental not production-ready.
