How to create linked list in javascript with ES6 classes

Intro

In this post, I'd like to share my implementation of LinkedList in JavaScript using mechanism of ES6 Classes.

LinkedList

class LinkedList {
    constructor() {
    this.head = new Node("", null);
  }
  
  addNode(node) {
    let curr = this.head;
    while(curr.next) {
      curr = curr.next;
    }
    curr.next = node;
  }
}

Node

class Node {
    constructor(data, node) {
    this.data = data;
    this.next = node;
  }
}

How to use it

let linkedList = new LinkedList();

// add some nodes
linkedList.addNode(new Node("1", null));
linkedList.addNode(new Node("2", null));
linkedList.addNode(new Node("3", null));

// console.log nodes, just to verify that everything works fine ;)
let current = linkedList.head;
while(current.next) {
    console.log(current);
    current = current.next;
}
