Implementing a Queue in JavaScript with Array

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 start a brand-new chapter — Queue 🧠 — one of the most important data structures in DSA! You’ll learn step-by-step what a Queue is, how it follows the FIFO (First In, First Out) principle, and where it’s used in real-world applications and DSA problems. We’ll go through: - What is a Queue and how it works - Understanding the FIFO concept with real-life examples - Queue operations — Enqueue, Dequeue, Peek, isEmpty, isFull - Where Queues are used in DSA (BFS, Scheduling, Buffers, etc.) By the end of this video, you’ll clearly understand: How Queue differs from Stack (FIFO vs LIFO) Why Queues are essential in problem solving Real-life use cases like Printer Queue, Task Scheduling, etc. Foundation for upcoming topics like Circular Queue, Priority Queue, and Deque This is a concept + theory video, so make sure to watch till the end before we move to implementation in the next one! * Watch here → https://lnkd.in/gyWSuZ4V * Watch the complete DSA in JavaScript playlist here: https://lnkd.in/g2qrGaSH * Download the PPT for this topic here: https://lnkd.in/gnga7zf6

🚀 New Video Alert! Just uploaded a new video on my YouTube channel — CodingMeAaja 🎥 This time, I explained one of the most confusing but important JavaScript topics 👇 Pass by Value vs Pass by Reference in JavaScript In this video, I’ve shown how JavaScript actually handles data — why const objects can still be modified, and how this can cause unexpected bugs in real-world projects. I also shared a real example that I personally faced during development — something every developer runs into at some point. What you’ll learn: 👉 The difference between value and reference in memory 👉 Why const objects can still be changed 👉 How passing objects to functions really works 👉 A real-world case that caused confusion 👉 How to avoid data mutation bugs This video is part of my Everyday JavaScript Topics 💡 playlist — where I share small, practical concepts that actually help in daily development. #JavaScript #CodingMeAaja #WebDevelopment #Coding #Learning #Frontend #Backend #SoftwareEngineering #Nodejs https://lnkd.in/gq7ZzWTQ

🚀 New Video in our DSA in JavaScript Series! In this video, we start a brand new concept — Circular Linked List (CLL) 🔁 — and understand how it’s different from a normal linked list. You’ll learn what makes it circular, how the last node connects back to the first, and where it’s actually used in real-world applications 💻 💡 You’ll clearly understand: ✅ What is a Circular Linked List (Singly Circular) ✅ How it differs from a normal Linked List ✅ Types of Circular Linked Lists ✅ Real-life use cases & applications ✅ Beginner-friendly visual explanation 🎥 Watch here → https://lnkd.in/eBDp4aGy 📌 Watch the complete DSA in JavaScript playlist here: https://lnkd.in/g2qrGaSH 📂 Download the PPT for this topic here: https://lnkd.in/ePkkrs-e Short, simple, and beginner-friendly — perfect to understand Circular Linked List Introduction in JavaScript step by step! 🚀 #dsa #dsainjavascript #javascript #circularlinkedlist #linkedlist #codingtutorial #dsaforbeginners #datastructures #javascriptdsa #jdcodebase
