# Node.js

This guide explains how to use ADSJS with CommonJS module format which is usually default for Node.js projects.

To add ADSJS into your project run the following command in terminal (from project directory):

```bash
npm install ads-js
```

Then give it a try in your source code:

```javascript
const SinglyLinkedList = require('ads-js').SinglyLinkedList;
// or
const SinglyLinkedList = require('ads-js/lists').SinglyLinkedList;

const list = new SinglyLinkedList([1, 2, 3]);
const position = list.getLast();

console.log(position.element);
```
