Import
import { reduce } from "@typed/fx/RefChunk";Signatures
export declare const reduce: {
<A, B>(b: B, f: (b: B, a: A, index: number) => B): <E, R>(ref: RefChunk<A, E, R>) => RefSubject.Computed<B, E, R>;
<A, E, R, B>(ref: RefChunk<A, E, R>, b: B, f: (b: B, a: A, index: number) => B): RefSubject.Computed<B, E, R>;
};Why
Makes reduce a live projection of the chunk; consumers can sample it now or observe it without copying the source state.
Ownership and lifetime
The reduce view retains no independent state. An Effect read samples the source once; Fx observation follows later pushes and its observing Scope owns subscription cleanup.
Other public imports
These import paths expose the same declaration. Each page retains its own public name and signature.
