Merry Christmas, everyone! 🎄

As the year wraps up, I just want to say a massive THANK YOU for all the support you’ve shown ArjanCodes in 2024. Together, we’ve hit an incredible milestone—260k subscribers! 🎉

This week, I’m hitting the pause button to spend some quality time with my family (and maybe eat a suspicious amount of cookies 🍪). That means no new video this week—but don’t worry, I’ve got big plans and exciting ideas for 2025. I can’t wait to dive into a new year of coding, learning, and, of course, roasting bad code. 😏

In the meantime, if you missed last week’s Code Roast, now’s the perfect time to catch up! I reviewed and refactored Tom Donahue’s Data Validator CLI. 🔥

Here’s to an amazing holiday season and an even better year ahead. See you in 2025!

Cheers,

Arjan
