Yeah, I 100% agree that they're not good examples of the sort of problem you'll need to solve in a given language. That said, I still like them—at least enough

Yeah, I 100% agree that they're not good examples of the sort of problem you'll need to solve in a given language. That said, I still like them—at least enough to write this one, anyway!—because they're small, self-contained, and dive deep enough into the language internals that you can (start to) see the differences in the "world view" of the language. (Compare them to something like Advent of Code challenges—those are also small, self-contained, and unrealistic to real programming, which makes them pretty similar. But many of the early ones don't get deep enough into the language to really get a feel for how the language pushes you to think/approach problems)
