+# array-uniq [](https://travis-ci.org/sindresorhus/array-uniq)
+
+> Create an array without duplicates
+
+It's already pretty fast, but will be much faster when [Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set) becomes available in V8 (especially with large arrays).
+
+
+## Install
+
+```
+$ npm install --save array-uniq
+```
+
+
+## Usage
+
+```js
+const arrayUniq = require('array-uniq');
+
+arrayUniq([1, 1, 2, 3, 3]);
+//=> [1, 2, 3]
+
+arrayUniq(['foo', 'foo', 'bar', 'foo']);
+//=> ['foo', 'bar']
+```
