Linked lists are a linear data structure that consists of a sequence of nodes. Each node contains a value and a pointer to the next node in the list. Linked lists are dynamic, which means that they can grow and shrink as needed.
class Node {
constructor(value) {
this.value = value;
this.next = null;
}
}
class LinkedList {
constructor() {
this.head = null;
this.length = 0;
}
add(value) {
const newNode = new Node(value);
if (this.head === null) {
this.head = newNode;
} else {
let current = this.head;
while (current.next !== null) {
current = current.next;
}
current.next = newNode;
}
this.length++;
}
print() {
let current = this.head;
while (current !== null) {
console.log(current.value);
current = current.next;
}
}
}
const linkedList = new LinkedList();
linkedList.add(1);
linkedList.add(2);
linkedList.add(3);
linkedList.print(); // 1 2 3
