🎮 Download CSV of Steam Purchases (473b)

Much like my script to Download Steam Library List, I created a similar script to download your list of Steam Purchases as a CSV file.

It's not perfect because you'll have to filter out the refunds and other types of transactions. Someone on reddit requested me to make it and I figured it was something I wanted to do myself so I did.

My JS1024 Annual JavaScript Golfing Competition Submission

I'm happy to have something to submit to the JS1024 2024 competition. I just found out about the competition and realized that I have something to submit even if it's not aligned with the theme. I'm pretty sure I started and finished the project during the competition. See my submission here.

Title: 🏗 Stacking Game

Short Description: Press Space or tap on mobile! See how high you can go in this stacking game!

🏗️ Stacking Game

🕹️ Play Now

Whenever I see a simple game, I start thinking about its mechanics and how it might be implemented.

So then when it seemed like a good small weekend project, I went for it. I got it down to its bare mechanics.

In future iterations, I could add animations, backgrounds, title screen, scoreboard, etc.

🧙‍♂️ Calculating XP to Level for RPG Games

I was curious on how level was determined for games and I found an awesome article about it by Jake Lee.

But one important thing was not explained in this article, how is it implemented in JavaScript?!

He has provided implementations in a Google Sheet and Github Gist though. So that may be your preferred method.

In the latest iteration my code editor, I've made big practical improvements to

🌱 Random Seed Methods

I wanted to see what's out there and here's what I found.

I think this is decent set to study, but I'm mainly interested in the smallest implementation and not worried about if it's computationally random.

rand = max => Math.sin(++seed)**2 * 1e9 % max

Small Library

I was looking into CSV methods on StackOverflow which didn't have great answers. So I put together some solutions that I'd appreciate.

Here's an answer I made for "JavaScript array to CSV," which didn't have any solid answers.

I found a great solution for parsing CSV so I figured that my work is complete by including a great parseCSV solution I found a while ago by Trevor Dixon.
