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.

How does PyScript actually work?
This is the primary difference between Pyodide and projects like Transcrypt or Brython: rather than transpiling to JavaScript, you get the real-deal CPython interpreter running client-side in the user's browser. There are a few things that don't work out of the box, since CPython usually runs on a computer and the Browser environment has some unique restrictions (lack of low-level access to networking, for one), but most things do just work.

alternatives to the javascript ecosystem
In the past, I've personally used GWT to transpile Java to JavaScript in order to share some complex code modules that we needed to use on both the server and client for an enterprise application. In more recent years, I've been using Transcrypt to develop React/MUI applications that are coded in Python. So I'm able to use JS libraries that are proven to work great in a web browser, but use my preferred language to code to the API of those libraries. This approach is certainly not for everyone, but it can be a viable option in some cases.

What's your Python story?
I now use Python everywhere. Desktop (PySide), embedded (MicroPython), web dev (React via Transcrypt), mobile (Kivy), and just general scripting. I love the versatility of Python, the ease of reading it without the visual cruft of other languages, and the availability of existing libraries that do just about everything you can think of. I also agree with the OP on the welcoming attitude of the Python community. The fact that Python is used in so many different areas leads to many new learning experiences when talking to other Python developers.

After tearing my hair out writing JavaScript the last few days how close are we to Python in the browser?
Transcrypt is pretty usable for this.
-
What do you guys use python for?
Transcrypt transpiles Python into JavaScript in the same way that TypeScript gets transpiled into JavaScript. It lets Python code word with JavaScript libraries that can then be run in a web browser.

Graphs in Python web app
There are options for writing Python and transpiling it into JavaScript but, frankly, they suck (https://www.transcrypt.org/).

React JSX vs react with HMTL
Lol, I'll tell you but you're not gonna like it - I write React applications in Python using a Python-to-JS transpiler called Transcrypt, and the source needs to be valid lintable Python code, so no JSX.

Toward a TypeScript for C++"
In addition to the other comments -
TypeScript deliberately takes a "good enough" approach to improving JavaScript, instead of designing an ideal but incompatible approach. For example, its handling of [function parameter bivariance](https://www.typescriptlang.org/docs/handbook/type-compatibil...) is unsound but works much better with the existing JavaScript ecosystem. By contrast, a more academic functional programming language would guarantee a sound type system but would be a huge shift from JavaScript.
By analogy, Herb Sutter is arguing that something like the [C++ Core Guidelines](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines), with tooling help in this new Cpp2 syntax, can bring real improvements to safety. Something like Rust's borrow checker would bring much stricter guarantees, backed by academic research and careful design, but would be incompatible and a huge adjustment.

C++ is everywhere, but noone really talks about it. What are people's thoughts?
Another phenomenal resource is the ISO C++ core guidelines which is essentially a giant list of best practices of newer c++ features. These guidelines were a collaborative effort started by Bjarne Stroustrup who know a bit about c++. There is an entire section about resource management if you're interested in learning more about the newer facilities c++ offers in that regard to avoid the footguns, but there is a ton of other great information in there as well.
Take a look at Effective Modern c++ by Scott Meyers and the ISO c++ core guidelines. These resources are great for learning how to write better, more modern C++. I don't think it would be hard to grasp if you're already familiar with the language, just make sure to actually write some code which makes use of this stuff, otherwise it's easy to forget.
-
What are some C++ specific antipatterns that might be missed by C#/Java devs?
Look to the C++ Core Guidelines. It's not perfect, it has some flaws, including some sabotaging advice apparently adopted for political reasons. But at least it has some C++ authorities (Bjarne and Herb) as authors.

Rust fact vs. fiction: 5 Insights from Google's Rust journey in 2022
C++: Not memory safe and tons of ceremonial to avoid UB and have actually well defined objects, semantically: for example, rule of five. Needs to follow a huge number of "core guidelines", https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines, many of the most important are not automatically enforceable by tools. No enum types, invisible codepaths everywhere due to exceptions. Stupid textual-inclusion compilation model meaning that you need to manually track which headers should actually be included in a file (in particular, when reviewing changes to that file that may or may not render some header inclusions useless). Namespace system where the namespace is not inferred from the file/package, but explicitly declared in the file, meaning that name collisions are possible (and result in an ill formed program, no diagnostic required. Once had to debug a colleague's ODR violation that made even valgrind segfault... very fun afternoon) and should be watched for in review. No unsafe and anything could be UB, so have to be paranoid about everything that is being done.
