Description

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: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, HashMapsWe 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.
