We can make the properties and methods private using closure and IIFE (Immediately Invoked function expression). Let stack = new stackUsingLL() //creating new instance of Stack Return the length of the stack //Return the size of the stackĬheck if stack is empty //Check if stack is emptyĬomplete code for stack using linked list //Stack using linkedlist To convert the stack to an array, we can copy all the items to the array and return it. While peeking just return the first item in the list. To remove an item from the stack we can just make the head to point the very next element. Stack using linkedlistĪs in the stack new item are added on the top, If the head is empty then the new node will be the first element, else we will make all the new node of the linked list to be the first node by assigning all the old nodes to the new node. While implementing stack we will use length to keep track of the size of the stack and head to keep track of the list. We will see two different methods to implement stack using linked list in javascript. However, time complexity in both the scenario is the same for all the operations i.e. Linked list allocates the memory dynamically. Instead of using an array, we can also use a linked list to implement a Stack. Implementing stack using single linked list In this article, we will discuss Stack implementation using Linked List in Java.
