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.

Why is Haskell considered good for writing a Compiler/Interpreter?
It is not nearly as annoying to left-factor parser combinators than it is to left factor CFGs, you just need to use appropriate combinators like chainl and chainr. And you'd want to abstract over common patterns in your CFG anyway, that is a strength of parser combinators! Compare this Earley example and my parser combinator example below.
What are some alternatives?
