Obviously we disagree on this and JavaScript (as I mentioned in the post), but wholeheartedly agree about c/c++. Trying to figure out how to share a C library, for example, is a huge mess.
However even if we exclude that I don’t like the way dependencies are handled. I much prefer Maven’s single repository instead of having a node_modules folder in every project.
I know a lot of people hate XML but it’s not that bad. And it was the popular thing in 2004, JSON and YAML were extremely new on didn’t have mindshare yet.
