Data Structures for Coding Interviews in JavaScript

Most people who struggle in technical interviews are not struggling because they do not understand JavaScript.They struggle because they cannot quickly identify which data structure a problem calls for before the clock runs out. That gap between knowing the material and performing under pressure is real, and it can be closed with the right kind of practice. This course comes from years of building systems at scale and interviewing hundreds of engineering candidates at top tech companies. What I saw repeatedly was that the candidates who performed best were not necessarily the ones who had studied the most. They were the ones who had trained themselves to recognize patterns quickly and respond with a clear, structured approach. You will work through the core data structures in JavaScript, including arrays, linked lists, stacks, queues, trees, heaps, graphs, and hash tables, and pair each one with the kind of interview problems where it actually shows up. The goal is not just to teach you how these structures work but to help you build the instincts to use them well when it counts. Whether you are preparing for your first technical interview or looking to improve after a few that did not go as planned, this course will give you practical skills you can put to use right away.
