# make-unique

Creates and makes an array without duplicates. Even with array of objects with a specified matcher.

If no `matcher` specified, it will use [`Set`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set) if `Set` is available in V8.

## Install

```sh
$ npm install make-unique --save
```

## Usage

```js
let unique = require('make-unique')

unique([1, 2, 3, 1]) // [1, 2, 3]
```

### unique(array, matcher)

- **array** `Array` the input array
- **matcher** `function(a, b)` if `matcher` returns `true`, then it will treat `a` equals to `b`.

Cleans an array of objects with a specified filter to tell `unique` how to determine if two items are the 'same'

```js
unique([
  {a: 1},
  {a: 2},
  {a: 1}

], (a, b) => {
  // if `a` and `b` contain the same `.a`, they are the 'same'
  return a.a === b.a
})
// [
//   {a: 1},
//   {a: 2}
// ]
```

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.
