70+ JavaScript Challenges: Data Structures & Algorithms [Brad Traversy]

Enhance your coding skills with 70+ JavaScript challenges covering data structures and algorithms. Learn how to ace coding interviews, master data structures, and understand sorting algorithms. Suitable for all levels, taught by Brad Traversy, a highly-rated Full Stack Web Developer


What you'll learn

  • Explore 70+ coding challenges from beginner, intermediate and advanced levels
  • Ace coding interviews by learning how to solve problems with iteration, recursion, array methods & more
  • Master data structures like stacks, queues, linked lists, trees, maps and hash maps
  • Learn about sorting algorithms like bubble sort, insertion, merge and quick sort
  • Full sandbox with explanations and Jest tests for every challenge
  • You do NOT have to take on the challenges alone. Follow along and learn from the explanations



  • You should know JavaScript & programming fundamentals


Most of my students know me for my practical, project-based courses and tutorials. I wanted to create something to give you more fundamental skills for problem solving. That's where the idea for this challenges course came from. I want to take my down-to-earth explanations to help you get a better understanding of the code that you write and help you write more efficient code.


This course is for all levels as long as you have a basic understanding of things like loops, functions, arrays, etc. We are writing JavaScript in this course, but about 95% of it can translate to any other language. So even if you are a Python, PHP or C# developer, you can still follow along.


Basic Challenges:

We start with a bunch of basic challenges that have to do with iteration and loops. Things like FizzBuzz and string reversals. These are very popular questions for entry-level interviews. We also move on to solving problems with high order array methods like filter and map.



Recursion is one of the toughest things to learn in programming. We have an entire section dedicated to it with challenges that we solve using recursion.


Time & Space Complexity:

We talk about how to measure an algorithm or function's efficiency by using time and space complexity to see how the runtime and memory scale when inscreasing the input.


Data Structures: Stacks, Queues, Trees, Linked Lists, Graphs, HashMaps

We go over all of the common data structures and create our own implementation of them using JavaScript classes, but like I said, you could use any language. We also learn how to traverse them and complete challenges using them.


Sorting Algorithms:

We get into different sorting algorithms like bubble sort, insertion, selection, merge and quick sort. These are popular topics for interviews.

Who this course is for:

  • Developers that want to build better foundational problem solving skills and pass job interviews
