Learn Queue Data Structure in JavaScript - DSA Series

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

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

💻✨ Practicing JavaScript Arrays! Today, I explored one of the most important topics in JavaScript — Arrays. From creating arrays to applying methods like push(), pop(), shift(), unshift(), map(), and filter(), I learned how powerful arrays can be in managing and manipulating data efficiently. 🧠 Key Concepts I practiced: Creating and accessing array elements Iterating through arrays using loops Using built-in methods for transformation Understanding how arrays make data handling easier in JavaScript Every small step in coding adds up to big progress! 🚀 #JavaScript #WebDevelopment #CodingJourney #LearningByDoing #FrontendDevelopment #JSArrays #WomenInTech #PracticeAndProgress

🚀 Day 7 of My 30 Days of JavaScript Journey ✅ Challenge: Array Reduce Transformation (LeetCode #2626) Write a function reduce(nums, fn, init) that processes each element of the array using the given reducer function fn, starting from an initial value init. This function should accumulate results sequentially and return the final value — implemented without using the built-in Array.reduce() method. 💻 Language Used: JavaScript ❓ Problem Link: https://lnkd.in/gxsp26cz 💡 Solution: https://lnkd.in/giZj_hYw 🧠 Concept Highlighted: This problem deepened my understanding of accumulator functions, data aggregation, and sequential computation in JavaScript. It helped me explore how the powerful reduce() method works behind the scenes — a key tool for transforming and summarizing data efficiently. #Day7 #JavaScript #LeetCode #30DaysOfCode #CodingChallenge #WebDevelopment #FrontendDevelopment #LearningEveryday #ProblemSolving #FunctionalProgramming
