When and where I can, I’ll be trying to complete the advent of code challenges in appscripts. You can follow along here … I find these sorts of exercises really valuable. It makes you think about the language you’re using very carefully. – Adam Morris
In the Google Apps Script Community Google Group Adam Morris is participating where he can in the Advent of Code
Advent of Code is an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.
