alt

import { alt } from "https://github.gh-proxy.cn/raw.githubusercontent.com/baetheus/fun/main/sync_either.ts";

Provide an alternative SyncEither if the current one fails.

@example

import { alt, left, right } from "./sync_either.ts";
import { pipe } from "./fn.ts";

const result = pipe(
  left("error"),
  alt(right("fallback"))
);

const value = result(); // Right("fallback")

function alt<A = never, B = never>(tb: SyncEither<B, A>): (ta: SyncEither<B, A>) => SyncEither<B, A>;

alt<A = never, B = never>(tb: SyncEither<B, A>): (ta: SyncEither<B, A>) => SyncEither<B, A>
