A curated list of advent calendars that will help you become a better developer.
Some Advent Calendar events are just good'ol coding challenges and some are articles related to web technologies, languages, UI/UX, Agile, etc
I wasn't sure how to categories these so its just two categories that make the most sense to me. But all suggestions are welcome!
Feel free to make a Pull Request to add other Advent Calendars that would help web developers.
