id
import { id } from "https://github.gh-proxy.cn/raw.githubusercontent.com/baetheus/fun/main/fn.ts";A thunk over the identity function. It allows one to constrain an identity to a specific type.
@example
import { id } from "./fn.ts";
const idString = id<string>(); // (s: string) => string
const idNumber = id<number>(); // (n: number) => number
const result1 = idString("Hello"); // "Hello"
const result2 = idNumber(1); // 1
