# dedupe

[![Build Status](https://travis-ci.org/Sab94/dedupe.svg?branch=master)](https://travis-ci.org/Sab94/dedupe)

removes duplicates from your array.

## Usage

### primitive types

```typescript

import { dedupe } from 'https://raw.githubusercontent.com/Sab94/dedupe/master/mod.ts'

var a = [1, 2, 2, 3]

var b = dedupe(a)

console.log(b)

//result: [1, 2, 3]

```

### complex types

Here the string representation of the object is used for comparism. The mechanism is similar to JSON.stringifing but a bit more efficient.

That means that `{}` is considered egal to `{}`. 

```javascript

import { dedupe } from 'https://github.com/Sab94/dedupe/blob/master/mod.ts'

var aa = [{a: 2}, {a: 1}, {a: 1}, {a: 1}]

var bb = dedupe(aa)

console.log(bb)

//result: [{a: 2}, {a: 1}]

```

### complex types types with custom hasher

```javascript

import { dedupe } from 'https://github.com/Sab94/dedupe/blob/master/mod.ts'

var aaa = [{a: 2, b: 1}, {a: 1, b: 2}, {a: 1, b: 3}, {a: 1, b: 4}]

var bbb = dedupe(aaa, value => value.a)

console.log(bbb)

//result: [{a: 2, b: 1}, {a: 1,b: 2}]

```
