left

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

Create a FnEither that always returns a Left(B).

@example

import { left } from "./fn_either.ts";

const leftNumber = left(1);

const result = leftNumber(0); // Left(1);

function left<B, D = unknown, A = never>(left: B): FnEither<D, B, A>;

left<B, D = unknown, A = never>(left: B): FnEither<D, B, A>

D = unknown

A = never

left: B

FnEither<D, B, A>
