The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
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.

Functional Programming in Lean – a book on using Lean 4 to write programs
Lean is currently moving to the 4th iteration which is the first intended to be a general-purpose programming language. It "is currently being released as milestone releases towards a first stable release". For now the main goal is to port mathlib to the new version, and then they will concentrate on the compiler. So it is not production ready. But that doesn't mean it is not suitable for building any programs now. There is a simple raytracer written in Lean [1]. I have built a chip8 interpreter with it and the only problem was the lack of an ecosystem, meaning I had to build the necessary libraries myself.
Now it has a RC GC and boxes everything >= 64 bits, and as the compiler isn't polished it is probably significantly slower. In the referenced raytracer repo you can find rendering time compared to the C implementation (Lean is 25x slower, but that was a year ago).

We Are Doomed: A pessimistic point of view of "modern software engineering"
Neither Apple nor Microsoft want any usable multiplatform graphics API. For this reason, none of them delivers such a thing.
If you want a multiplatform graphics API, you should use a library which implements such API on top of these native OS-specific APIs.
I have good experience with that one: http://diligentgraphics.com/diligent-engine/ I’ve used it couple times on Windows with D3D12 backend, and on Linux with GLES 3.1 backend.

The Ultimate Cross-Platform Rendering Engine?
Diligent Engine: They say their engine is the successor of bgfx, but I'm not rly into that topic.

Collecting the best C++ practices
Diligent Engine. A Modern Cross-Platform Low-Level 3D Graphics Library and Rendering Framework Tweet.
- Diligent Engine 2.5.3 is out: path tracing tutorials, render state cache, hot shader reload and more
- Good repos for beginners to browse that follow best modern C++ practices (including testing, static analysis etc...)
- Check out a new path tracing tutorial in Diligent Engine that shows how to use a render state packager to build pipeline states off-line and pack them into archive so that they can be loaded fast at run time.

Improving my CPP skills
Read other people's code (I recommend modern small to medium sized github projects, because large ones can be overwhelming) or else you will forever stay in your bubble of how things are done. For example, I had learned a thing or two by using (and code browsing) diligent engine's source.

A Rant on Developers
I'm not speaking out of my ass, either, I have very actively followed low-level development being done towards open-source engines such as Diligent and Wicked. I personally am a contributor to the latter engine, as well. It is baffling to me that independent developers don't support this platform.
