unwrap

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

Just like the first function, unwrap returns the first value in a pair.

@example

import { pair, unwrap } from "./pair.ts";

const result = unwrap(pair(1, 2)); // 1

function unwrap<A, B>([first]: Pair<A, B>): A;

unwrap<A, B>([first]: Pair<A, B>): A

[first]: Pair<A, B>
