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.

The JavaScript Ecosystem Is Delightfully Weird
When I last looked, it seemed like WASM blobs just take arrays of numbers and return arrays of numbers. No objects, strings, or DOM elements, so I think it'd be tough to do web dev in wasm as it stands. And you need javascript glue if you want anything in the way of side effects.
There is, however, quite a bit you can do in it. TeX has been compiled to wasm[1], it's about 600kb uncompressed 90k compressed (the memory image with latex loaded is about 6MB compressed though - latex is a beast). I think anything computationally intensive would be a good candidate for wasm (it has int64).

Math Rendering Is Wrong
I implemented a TeX engine in WebAssembly so you really can run TeX in the browser. You can see a demo of this at https://tex.rossprogram.org/ and at https://github.com/kisonecat/web2js you can find a Pascal compiler that targets WebAssembly which can compile Knuth's TeX. Interesting primitives like \directjs are also implemented, so you can execute javascript from inside TeX. The rendering is handled with https://github.com/kisonecat/dvi2html for which I finally fixed some font problems.
To make it relatively fast, the TeX engine gets snapshotted and shipped to the browser with much of TeXlive already loaded. So even things like TikZ work reasonably well. There is of course a lot more to do! The plan is to convert ximera.osu.edu to this new backend by the fall.

Math Rendering Is Wrong
I have use MathML with Latex2mathml python library https://github.com/roniemartinez/latex2mathml. And is great, the fact that you can render math without a single line of java script. But at the end, only Firefox fully supports MathML, without Chrome support is kind of useless.
What are some alternatives?
dvi2html - Device independent (DVI) file format parsing with node
KaTeX - Fast math typesetting for the web.
remark - markdown processor powered by plugins part of the @unifiedjs collective
SciencePlots - Matplotlib styles for scientific plotting
js-in-css-rt - JS-in-CSS runtime
