70+ JavaScript Challenges - Data Structures and Algorithms

Updated in May 2025. This course now features Coursera Coach! A smarter way to learn with interactive, real-time conversations that help you test your knowledge, challenge assumptions, and deepen your understanding as you progress through the course. Master JavaScript data structures and algorithms through 70+ hands-on coding challenges. This course takes a practical approach, helping you strengthen your problem-solving skills while improving your coding efficiency. You'll work through real-world scenarios, from basic string manipulations to advanced graph traversals, developing a deep understanding of algorithmic thinking. The journey begins with fundamental concepts, such as recursion and higher-order functions, before progressing to essential data structures like stacks, queues, linked lists, hash tables, and binary trees. You'll implement each concept through interactive challenges that reinforce learning. You'll also explore time and space complexity, ensuring you write optimized code. As you advance, you'll tackle graph algorithms, sorting techniques, and in-depth exercises on searching and traversal methods. With each challenge, you'll enhance your ability to write efficient JavaScript code while developing key skills needed for coding interviews and technical assessments. This course is ideal for JavaScript developers, coding enthusiasts, and those preparing for technical interviews. A basic understanding of JavaScript syntax is recommended, but no prior experience in data structures and algorithms is required. Whether you're a beginner looking to level up or an intermediate developer sharpening your skills, this course will take your coding expertise to new heights.
