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.

Python is in the browser. No idea if this will lead to chaos or harmony...
oh good, maybe we can now use python's javascript interpreter in browsers https://github.com/amol-/dukpy

Web Browser Engineering
I was interested to see that this uses the DukPy wrapper around Duktape for the JavaScript interpreter: https://browser.engineering/scripts.html
This made me start digging into whether this was considered a "safe" way of executing untrusted JavaScript in a sandbox.
its not completely clear to me if DukPy currently attempts safe evaluation - it's missing options for setting time or memory limits on executed code for example: https://github.com/amol-/dukpy
There's a QuickJS Python wrapper here which offers those limits: https://github.com/PetterS/quickjs
I'm pretty paranoid though any time it comes to security and dependencies written in C, so I'd love to see a Python wrapper around a JavaScript engine that has safe sandbox execution as a key goal plus an extensive track record to back it up!

My friend thought that 1 is a string in Python
I didn't write it, but here you go. Thanks to the fact that you can pass Python arguments to the JavaScript function, it will nicely cast them for you (via JSON) and make them behave per a Javascript object, which can then do some funsies to make it act like a string.

YouTube-dl has a JavaScript interpreter written in 870 lines of Python
To understand why, I have a far simpler tool that focuses on a subset of sites (adult content video aggregators)
https://github.com/kristopolous/tube-get
It too deals with this problem but does so in a way that'd be easy to maliciously sabotage
Look right about here https://github.com/kristopolous/tube-get/blob/master/tube-ge...
Add to why this exists, this was originally written between about 2010-2015 or so so it technically predates the yt-* ecosystem.
The tool still works fine and it's not a strict subset of yt-dlp or YouTube-dl because being a different approach, although it's overall site coverage is smaller, I've had it be a "second try" system when yt-* fails and it comes up with success maybe about half the time
