🚀 New Video in our DSA in JavaScript Series! In this video, we continue our Stack chapter 📚 — and learn how to implement a Stack using Linked List in JavaScript 💻 You’ll understand how a linked list can be used to make a dynamic stack, where size isn’t fixed — and how operations like push(), pop(), peek(), and isEmpty() work step by step ⚙️ We’ll build everything from scratch using classes, link nodes dynamically, and compare it with the array-based stack 👇 💡 You’ll clearly understand: ✅ How to implement Stack using Linked List in JavaScript ✅ Stack operations — push(), pop(), peek(), isEmpty() ✅ Why Linked List-based Stack is more flexible than Array-based Stack ✅ Step-by-step implementation in VS Code ✅ Complete code + PPT included 🎥 Watch here → https://lnkd.in/eVCcWrZ3 📌 Watch the complete DSA in JavaScript playlist here: https://lnkd.in/g2qrGaSH 📂 Download the PPT for this topic here: https://lnkd.in/exZSucJj #dsa #dsainjavascript #javascript #stack #linkedlist #datastructures #codingtutorial #dsaforbeginners #jdcodebase #javascriptdsa #stacktutorial

New Video in our DSA in JavaScript Series! In this video, we continue our Stack chapter and solve two very popular stack problems in JavaScript. You’ll learn step-by-step how to: Evaluate a Postfix Expression using Stack Find the Next Greater Element (NGE) using an efficient O(n) stack approach Both problems are extremely important for interviews and will help you clearly understand how the LIFO (Last In, First Out) principle works in real DSA problems. We’ll break down the full logic with: - Concept explanation - Step-by-step dry run - Complete JavaScript implementation inside VS Code You will clearly understand: - How Stack helps in Expression Evaluation - Why we use Stack for NGE problems - Internal working of push() and pop() - How Stack makes the solution optimal in O(n) time * Watch here → https://lnkd.in/g2-TRV_C * Watch the complete DSA in JavaScript playlist here: https://lnkd.in/g2qrGaSH * Download the PPT for this topic here: https://lnkd.in/gBiwxSG5

New Video in our DSA in JavaScript Series! In this video, we continue our Queue chapter — and learn how to implement a Queue using Array in JavaScript step by step You’ll clearly understand how the FIFO (First In, First Out) principle works in real code, and how to perform all the core operations of a Queue - Implement Queue using Array - enqueue() → Add element at rear - dequeue() → Remove element from front - peek(), isEmpty(), isFull() → Utility operations - Practical demo and explanation in VS Code We’ll also discuss how the front and rear pointers change with each operation, and understand why removed elements are not deleted from the array — only skipped logically. By the end of this video, you’ll have a working Queue implementation and a solid understanding of how linear queues work in DSA. * Watch here → https://lnkd.in/ghnrpUUb * Watch the complete DSA in JavaScript playlist here: https://lnkd.in/g2qrGaSH * Download the PPT for this topic here: https://lnkd.in/gnfdEiKJ
