The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Calling linked lists Haskell's "primary data structure" seems off-base to me. Yes, there's String, yes, there's built-in syntax for List... but there's also everything in containers, and vector is pretty easy to use in practice, though it would probably be good for more learning material to mention it more prominently.
Is a a MONAD in Haskell just the functional equivalent of a generic type (such as in C#) and how do MONADs enable things like saving data?

Haskell has much more sophisticated immutable data structures, you can find them in the "containers" package: https://hackage.haskell.org/package/containers

I asked this on the libraries mailing list but thought posting here would bring in potentially more responses. I made a recent change to the behaviour of lookup and find (see here for more details: https://github.com/haskell/containers/pull/800).

Rust has nothing on Haskell. containers, which might as well be considered part of the standard library, has been out for almost 14 years and is still 0.x

When I was first learning I did a bunch of leetcode/codewars to get familiar with the containers library and GHCI repl workflow. Then using Real World Haskell as a reference I implemented a few coreutils to play with IO.

A super-ugly Dijkstra implementation with psqueues for priority queues. Before I took them into use the first part took ~10 sec, after that it's ~60ms, and 2.5s for the second part. I believe, there's still room for optimization, but it's enough for today.
