Working Through The Last Algorithms Course You'll Need by ThePrimeagen

What is it?

Well, The Last Algorithms Course You’ll Need is a course on Frontend Masters taught by ThePrimeagen. It covers quite a few fundamental data structures (lists, arrays, queues, maps, graphs) and algorithms (search, sort). ThePrimeagen is entertaining (he’s a youtuber and twitch streamer) and makes the videos fun.

What I’m doing and WHY?!

I’m working through the course and taking some notes as a I go. I’ll also be implmenting the algorithms and data structures in Javascript. I’m doing it for two reasons:

1. I feel like I’m a little too comfortable in my Python safe space, and I want to explore another language. Javascript is something that keeps popping up as something that would be useful to know beyond being able to read through what someone wrote.
2. I want to learn more about data structures and algorithms. I think they’re interesting.

The Plan

I’m a few videos into the course already. I’m going to stay ahead of this blog by 1-2 hours of videos so that when I’m writing a summary or doing the katas, I’m less likely to remember exactly what ThePrimegen did. So,

1. Watch an hour or two of video.
2. Write a description of the topics covered (algorithm, data structure, whatever it is)
3. Do the katas
4. ???
5. Profit
