> JavaScript array.filter() compatible unique filter

As all unique libraries are used as a function and not within the easily
stackable and immutable arr.format() style I made my own.

## Install

Node.js:

```bash
npm install array-filter-unique
```

Deno:

```ts
import {/* ... */} from "https://deno.land/x/array_filter_unique/mod.ts";
```

## Usage

```js
import { arrayFilterUnique } from "array-filter-unique";

['a', 'a', 'b', 'c']
  .filter(arrayFilterUnique());
//=> ['a', 'b', 'c']

[{name: 'Alice', …}, {name: 'Peter', …}, {name: 'Alice', …}}]
  .filter(arrayFilterUnique(o => o.name));
//=> [{name: 'Alice', …}, {name: 'Peter', …}]
```

## Migrate from v2 to v3

```diff
-const arrayFilterUnique = require('array-filter-unique');
+import {arrayFilterUnique} from 'array-filter-unique';

 someArray.filter(arrayFilterUnique());
```

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.
