🎒 Requierments

No requierments, just install or grab from the CDN.

🚀 Quickstart

Install

NodeJS

Install using the terminal:

npm install @danielcobo/getunique

Require the module:

const getunique = require('@danielcobo/getunique');

_{Note: In case you're wondering, @danielcobo/ is just a namespace scope - an NPM feature. Scopes make it easier to name modules and improve security.}

Browser

Declare it as a global variable named getunique by including this script before any script you want to use it in:

<script src="https://cdn.jsdelivr.net/npm/@danielcobo/getunique@1/dist/iife/getunique.min.js"></script>

Or import it as an ECMAScript module:

import * as getunique from 'https://cdn.jsdelivr.net/npm/@danielcobo/getunique@1/dist/esm/getunique.min.js';

Also, feel free to download the file if you prefer not to use jsdelivr. In that case just replace the url with the relative file path.

Example use

const arr = getUnique(['one', 'two', 'two', 'three']); //'one', 'two', 'three'

For details see documentation below.
