HN comment orderThe documentation and code quality is all good. The implementation choices leave some things to be desired. The Queue and Stack implementations are Linked Lists instead of array backed, the hash table is closed instead of (the only barely more complicated) open Robin hood hash table scheme, the union-find/disjoint-set implementation doesn't have path compression or rank unions. Overall very good, but it could be Great (tm) with just a little bit of work.
I would like to point out that a possible reason this repo is so popular is that Javascript is more accessible to more people than any other programming language today and this shows the demand to meet these programmers halfway and help further their education. I think most js devs know Javascript is a poor choice for this, but they have to walk before they can run. I tend to think of Javascript as the language that fulfills the promises…
