JavaScript Linked Lists: Foundations of Data Structures

Data structures are the building blocks of efficient software, yet many developers struggle to implement them in JavaScript. Understanding how linked lists work under the hood is essential for writing optimized algorithms and passing technical interviews. This text-based course guides you through the core concepts of linked lists, helping you transition from basic arrays to dynamic, pointer-based data structures. You will learn to construct, manipulate, and optimize various types of linked lists using modern JavaScript class syntax. What you'll learn: Understand the core differences between arrays and linked lists in memory management; Implement singly linked lists from scratch using modern JavaScript classes; Master pointer manipulation techniques for insertion, deletion, and traversal operations; Build doubly linked lists and analyze their performance trade-offs; Solve common algorithmic challenges and interview questions involving linked lists; Apply modern JavaScript features like private class fields and clean ES6+ syntax. You will start with the fundamental theory of nodes and pointers, progress to building fully functional singly and doubly linked lists, and finish by solving practical coding challenges. This course is designed for beginner to intermediate JavaScript developers who want to strengthen their computer science fundamentals without needing prior data structure experience.
