class Node {

        this.data = data;
        this.next = null;
    }
}

class LinkedList {
    constructor() {
        this.head = null;
    }

    append(data) {
        let newNode = new Node(data);
        if (this.head === null) {
            this.head = newNode;
        } else {
            let current = this.head;
            while (current.next !== null) {
                current = current.next;
            }
            current.next = newNode;
        }
    }

    printList() {
        let current = this.head;
        while (current !== null) {
            console.log(current.data);
            current = current.next;
        }
    }
}

let list = new LinkedList();
list.append(10);
list.append(20);
list.append(30);
list.printList(); // Output: 10 20 30

A stack is a LIFO (Last In, First Out) data structure. The most recent element added is the first one to be removed.
