Practical helpers to unfunctionalize fp-ts types

## Description

Functional programming is powerful, but not always the most practical. This package encourages using functional programming in Typescript using [`fp-ts`](https://github.com/gcanti/fp-ts) by providing a very practical way to interact with the broader, imperative codebase.

## Install

`unfun-ts` is a utility library for `fp-ts`. Therefore `fp-ts` is a peer dependency of `unfun-ts`.

```

yarn add unfun-ts

yarn add fp-ts@^2.0.0

```

## Usage

```ts

import * as UE from "unfun-ts/lib/Either";

import * as E from "fp-ts/lib/Either";

import { pipe } from "fp-ts/lib/pipeable";

// const nullyValue: undefined | number;

try {

  const value = pipe(

    nullyValue,

    E.fromNullable("nully"),

    UE.getOrThrow(),

  );

} catch (bad) {

  console.error(`The value was ${bad}`);

}

```
