Functional way of throwing errors in JS/TS

## Why?

Have you ever tried to do this?

```ts

callback(() => throw new Error("Not implemented"));

// or this

doStuff(value ?? throw new Error("No value provided"));

```

But got `Uncaught SyntaxError: Unexpected token 'throw'`.

With `panic-fn` it works as expected.

```ts

callback(() => panic("Not implemented"));

// or this

doStuff(value ?? panic("No value provided"));

```

You can also throw custom errors:

```ts

panic(new SyntaxError(`Unexpected token 'throw'`));

```

## Installation

### Node

```bash

npm i panic-fn

```

```ts

import { panic } from "panic-fn";

```

### Deno

```ts

import { panic } from "https://deno.land/x/panic_fn/mod.ts";

```

## Module info
