๐ Requierments
No requierments, just install or grab from the CDN.
๐ 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.
