I spent a lot of time trying to figure out why I was getting "root is not a function" while trying to use the MinPriorityQueue in javascript, because looking at the code in github it seemed correct. I later realised that it was updated 2 weeks ago and the version used in neetcode is older than this. It would be great if the neetcode UI could report what version of these packages it's using so that issues can be diagnosed against the correct version.
