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.

YouTube-dl has a JavaScript interpreter written in 870 lines of Python
Embedding V8 can work quite well: https://github.com/sqreen/PyMiniRacer
You probably have to emulate some of the DOM, but you can interact directly with whatever obfuscated/packed scripts in a more lightweight and secure way than driving an entire browser.

connecting languages
First learn what forms computer code can be in. Source code combine js and python or to combine c and C++ object code with a linker or at runtime if you want to shell out and run from the prompt

Web Browser Engineering
If you want battle-hardened, I figure you can't do better than V8. Here's a Python wrapper that I've poked at a bit (it's not quite 100% feature-complete but it seems to essentially work): https://github.com/sqreen/PyMiniRacer

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.
What are some alternatives?
quickjs - Thin Python wrapper of https://bellard.org/quickjs/
Playwright - Playwright is a framework for Web Testing and Automation. It allows testing Chromium, Firefox and WebKit with a single API.
jsx-control-statements - Neater If and For for React JSX
tube-get - A tube-site downloader
prettier - Prettier is an opinionated code formatter.
mini_racer - Minimal embedded v8
pyodide - Pyodide is a Python distribution for the browser and Node.js based on WebAssembly
Duktape - Duktape - embeddable Javascript engine with a focus on portability and compact footprint
vado - A demo web browser engine written in Haskell
nitter - Alternative Twitter front-end
binjs-ref - Reference implementation for the JavaScript Binary AST format
