Describe your suggestion

As I understand it, when growing a hash map, it is necessary to rehash all existing keys. The course currently says "To grow our buckets, we create a new buckets list that is double the size of the old buckets list, then we copy all nodes over to the new buckets." That wasn't very clear to me, and skimming solutions from students on the hashmap project, 2 out of 3 just mapped the existing keys directly to the larger hash map without rehashing them. It would certainly benefit from more explanation.

I agree this is a good idea, and thank you for making this issue.

Might be something we handle as part of #27174, but I'll keep this open in case we don't.
