250+ DSA Interview Questions JavaScript Coding - FAANG Ready

This course contains the use of artificial intelligence. DSA Interview Questions JavaScript Coding - FAANG Ready is a complete DSA interview preparation course with 250+ coding problems solved in JavaScript. Every single question you'll find here is the type that gets asked at companies like Google, Amazon, Microsoft, Meta, and top product startups.We don't just throw problems at you. We teach you the thinking process behind every solution — why this approach, why not that one, what's the time complexity, what's the space complexity, and most importantly — how would you explain this in a real interview.What makes this different from other DSA courses?Honestly, most DSA courses either go too theoretical or just show you the answer without explaining the thought process. This course does neither.Here's what you actually get:Every problem is solved in JavaScript — not Java, not Python. Real JS syntax, real JS methods, things you already know.Problems are organized by patterns, not randomly. You'll do all Sliding Window problems together, all Two Pointer problems together. This is how your brain builds pattern recognition.We cover 14 topics — Arrays, Strings, Linked Lists, Stacks, Queues, Trees, Graphs, Heaps, Tries, Recursion, Backtracking, Dynamic Programming, Sorting, and Bit Manipulation.Each solution comes with a step-by-step explanation — not just code dumped on the screen.We discuss multiple approaches for most problems — brute force first, then optimized. Because that's how real interviews go.By the time you finish this course, you'll be able to look at any DSA problem and immediately identify which pattern to apply. You'll walk into your next technical interview with actual confidence — not the fake kind where you hope the interviewer asks something you memorized, but the real kind where you know you can figure it out even if you've never seen that exact problem before.You'll also have solved 250+ problems in JavaScript — which means your problem-solving muscle will be strong. Companies like Google and Amazon don't expect you to have seen every problem. They want to see how you think. This course trains exactly that.Topics Covered:Arrays StringsLinked ListsStacks QueuesTrees Binary Search TreesGraphs (BFS, DFS, Topological Sort)Dynamic Programming (Knapsack, LCS, LIS and more)Recursion BacktrackingHeaps Priority QueuesTriesSorting Searching (Binary Search patterns)Greedy AlgorithmsBit ManipulationMath Number Theory
