Import

import { RefArray } from "@typed/fx";

Access RefArray.reduceRight through the imported RefArray export. Its declaration below describes the member.

This public exposure is a re-export. Its import path is supported; declaration documentation is shared with the other public exposures below.

Signatures

export declare const reduceRight: {
    <A, B>(b: B, f: (b: B, a: A, index: number) => B): <E, R>(ref: RefArray<A, E, R>) => RefSubject.Computed<B, E, R>;
    <A, E, R, B>(ref: RefArray<A, E, R>, b: B, f: (b: B, a: A, index: number) => B): RefSubject.Computed<B, E, R>;
};

Why

Makes reduce right a live projection of the array; consumers can sample it now or observe it without copying the source state.

Ownership and lifetime

The reduce right 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.
