import * as mod from "https://deno.land/x/result_js/mod.ts";

```

npm:

```bash

npm i @miyauci/result

```

## Usage

Type [Result](https://deno.land/x/result_js/mod.ts?s=Result) represents an

success or failure.

```ts

import {

  Err,

  Ok,

  type Result,

  unwrap,

} from "https://deno.land/x/result_js/mod.ts";

import { assertThrows } from "https://deno.land/std/testing/asserts.ts";

function divide(

  numerator: number,

  denominator: number,

): Result {

  if (!denominator) return Err("divide by 0");

  return Ok(numerator / denominator);

}

const opt = divide(100, 0);

assertThrows(() => unwrap(opt));

```

All [operators](https://deno.land/x/result_js/mod.ts#Functions) for

[Result](https://deno.land/x/result_js/mod.ts?s=Result) are separated from

prototype.
