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.

Lua: The Little Language That Could
it should be possible, the article mentions https://fengari.io/ (a Lua VM written in JavaScript)
-
PyScript
Other languages have done that :)
Lua in the browser: https://fengari.io/
And then you can use that to run Fennel, a Lisp that compiles to Lua https://fennel-lang.org/
I think TypeScript also has a script you can include that lets you put your TS code in a special script tag, and it gets compiled in-browser.

Upcoming interview with Roberto Ierusalimschy
Please stop this stuck in the mud nonsense. Anyone stumbling upon lua.org might think the project is dead already. The material is great, close to the best, but its presentation is pure shite. Not mobile friendly (what kinds of device do you think the majority of people in the Global South use?). We live in a world of code highlighting, none of that in PiL. We live in a world where Fengari allows Lua to run in the browser, does that make an appearance on lua.org, allowing users to immediately play with the language? Of course not! It's almost as if the Lua team is trying to push away potential users.

Fengari – Lua for the Browser
Lua 5.3’s not really a fork. It just has backwards-incompatible changes, as do 5.1, 5.2 and 5.4.
Otherwise yes, “Fengari implements Lua 5.3”. https://github.com/fengari-lua/fengari

Move over JavaScript: Back-end languages are coming to the front-end
Please note, my original comment was simply correcting the notion that JS is popular because it was especially well suited for working on the web. I see projects like Fengari[1] and would _love_ to use something like that but I recognize I can't impose an extra 300kb on end users just because I want to write in a more pleasant language to develop. I accept that JS is what we have, but I won't pretend like JS was the cream that rose to the top.

How I coded my way to victory in World of Warcraft
WoW's UI API is written in Lua. If you aren't familiar, Lua is a great little scripting language built on top of C, designed to be embedded into larger pieces of software. You can even, thanks to web assembly, run it in the browser. It has some quirks that take some getting used to (Lua's Arrays start at index 1 👀), but by and large it's great at what it does and can be found everywhere in computer game UIs.

CPython's main branch running in the browser with WebAssembly
> I’d expect MicroPython (or Lua/mruby/etc) could be an order of magnitude smaller. Still larger (and slower) than just using JavaScript, though.
Fengari [0], a Lua interpreter written in JS, is a little over 200Kb. (And was intentionally written in JS [1] because of a variety of reasons that made WASM not work that well.
200Kb isn't that bad of a price to pay to switch languages, on most websites. It'll be about the cost of a single image added to the page. And it's fairly performant.
For most sites, the costs in terms of requests and performance will be negligible compared to what you're trying to achieve.
And Fengari makes it nice and easy to interact with JS, too. Using React with Lua's syntax was what sold me on it. No ecosystem lockout, like I'd expect with most WASM ports.

PyScript
At https://hal9.com, we built components for data science com native JavaScript to avoid the waiting times and download overhead if Pyodide. We found out the best tools for doing data science in the browser are a combination of Arquero and D3 and TensorFlow.js. At least for now.
We wrote our findings of this and many other libraries here: https://news.hal9.com/posts/data-science-with-javascript
We are not using libfortran not gdpr, we are basically using whatever libraries are available for the web. Since most data scientists don't want to use JS per se, you can build the apps as blocks in the Hal9 site or using a soon-to-be-released Python/R package, see https://notebooks.hal9.com
Feel free to check out our repo as well, all the "primitives" / blocks code is in the scripts folder: https://github.com/hal9ai/hal9ai

Ask HN: Can you share websites that are pushing the utility of browsers forward?
https://hal9.com helps data scientists build faster web applications.
It uses WebGL and WebAssembly to process larger datasets, perform inference in the browser with TensorFlow.js, and enables running Python code with Pyodide.

Ask HN: What ML platform are you using?
If you want to build a web application on top of your ML project, give https://hal9.com a shot. We designed Hal9 with ease of use for deployment and maximum compatibility with web technologies that enable you to build ML apps with React, Vue, etc. We launched a couple months ago but could use some early feedback and users. Thank you!

Built data analysis platform optimized for web developers
BTW. If you are ever interested in helping us out, you can send a PR's to our GitHub repo. For instance, the summarize and convert blocks are here: https://github.com/hal9ai/hal9ai/blob/main/scripts/transforms/summarize.txt.js and https://github.com/hal9ai/hal9ai/blob/main/scripts/transforms/convert.txt.js
In addition, you can also use Hal9 as a standalone JS library for data analysis and skip the UX, see https://github.com/hal9ai/hal9ai
Thanks! Is actually all Vue. I like Vue better over React, just personal preference, React is great and probably better for large applications. The trickiest path is the code that executes the pipelines since it has to run dynamic JS code with dynamic parameter; made that open source to make sure people are not stuck with the product if they ever have to leave or want to scar outside the product: https://github.com/hal9ai/hal9ai
You can find more about this project at https://hal9.com — We allow you to edit any block with JavaScript and to export the analysis as as embeddable HTML. You can also use Python or NodeJS if you need more advanced functionality.

PyFlow – visual and modular block programming in Python
We are working in https://hal9.com which is language agnostic and allows you to compose different programming languages; however, we are focused at the moment at 1D-graphs but have plans to support 2D-graphs in the coming weeks.
If you want a demo or just time to chat, I'm available at javier at hal9.ai.

Mlflow, fastapi, streamlit template Project
We would love to help out since this is a perfect use case for https://hal9.ai; we are about to release our beta version that makes this as easy as copy-pasting code. You can find me at javier at hal9.ai to find some time to chat and give you a walkthrough of our code-to-api functionality.
