Why is Julia so great?

I looked at DuckDB to replace SQLite in some usecases, but their Julia package seems (1) not well-integrated, eg regarding julia tables support, (2) heavy in terms of dependencies (48 deps, many are nontrivial), and (3) as I understand, doesn’t use basic julia testing practices.
I didn’t even manage to run their tests when trying to improve (1):

Maybe they just don’t consider julia integration that important, idk.
