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.

I'm really liking Racket but...
I don't think there's any mature projects that compile to WASM yet, but there's been some steady progress on that front. There's also a dialect of Racket that transpiles to Javascript and a #lang that lets you write Javascript using Racket syntax.

Racketscript
The github page has more information: https://github.com/racketscript/racketscript
And to answer the questions every Schemer will have, no the runtime doesn't yet support tail calls or continuations.
- Anyone aware of Racket projects that are in need of contributors? I am experienced in PL design and have two months worth of spare time. I have never contributed to an opensource project before besides taureg.

A Tour of Lisps
> The problem with learning Lisp is `(a ,b c)
If you can understand "String ${interpolation}", you can understand list quasiquoting.
> But the problem remains: it only takes one wizard to make reading code impossible by outsiders.
This really is a Lisp meme. There are plenty of Lisp wizards like Guy Steele, Rich Hickey, and Matthew Flatt. The wizards perform the magical act of making code legible and intelligible. I have stumbled around several Clojure and Racket code bases and never felt like "I should understand this code but the features of Lisp make it impossible to know for sure." "Infinite power" macros and whatever are really only used sparingly and generally when it's impossible to achieve a goal otherwise. No one is doing (define + -).
> But this means no-one outside of the language/system developers know the language, this means Lisp tends to be write-only by design - not in the line-noise meaning, but in the obscure foreign language meaning.
I, as a Racket novice, have been able to add candlesticks [1] to the plot library without learning much about it. I have also debugged DrRacket (an IDE) to uncover that Racket GUI operations performed significantly worse if non-integer scaling was used [2]. At no point when I was going through Racket internal code did I ever feel it was write-only. In fact, it was quite convenient to modify Racket internal source code, rebuild, and test changes in a way that would be much more difficult in Java or C++.
> You certainly can not do that, but if you choose to not do that, why pick Lisp?
Built in rationals.
The ergonomics of defining [XML / JSON / etc] data as S-expressions and doing things like pattern matching on that data.
Great, coherent integration between GUIs, plots, statistics functions, and all the other bits of Racket's batteries inclusions.
You still have access to all the other great features that other languages have borrowed from Lisp like REPL development, package managers, good IDE tools, etc.
It is nice to learn the meta-syntax of parentheses once and know that the code will always look like that. No need to consider if some feature is implemented as a syntactically different new keyword, annotation, function call, or whatever. It'll always be a (feature).
> something you have to conciously work for with Lisp.
Plenty of languages have style guides, linters, static analysis tools, etc. to make sure the code conforms to certain restrictions. Lisp feels no different in this regard.
