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.

Eloquent JavaScript 4th edition (2024)
It's not as popular as typescript but not dead, it's consistently active [0] for a decade.

Current thoughts on TypeScript, type safety, and its competition/presence in the ecosystem?
One alternative that I found was flow, thought haven't used it. There is a bevy of languages that transpiles to JS, though some seemingly lost their attention over time. Can the bridge to WASM contribute to this or is that digressing from the topic?
-
Typescript vs Flow? and why?
I think you are mistaking Flow unmaintained for Flow actively maintained.

Hack and Flow are also written in OCaml.

I'll offer my two cents, since we're all taking another ride on the JavaScript hate train.
So... you're referring to flow?

Why Wolfram Tech Isn’t Open Source–A Dozen Reasons
It seems like Facebook doesn't have problem with releasing open source project [0] while keeping centralised control over it.

OCaml professionally
Facebook uses OCaml professionally, for [Flow](https://github.com/facebook/flow), their typechecker for JavaScript, and [Pyre](https://github.com/facebook/pyre-check), their typechecker for Python.

An Introduction to Temporal Logic (With Applications to Concurrency Problems)
I think most development occurs on problems that can't be formally modeled anyway. Most developers work on things like, "can you add this feature to the e-commerce site? And can the pop-up be blue?" which isn't really model-able.
But that's not to say that formal methods are useless! We can still prove some interesting aspects of programs -- for example, that every lock that gets acquired later gets released. I think tools like Infer[0] could become common in the coming years.

Enforcing Memory Safety?
Using infer, someone else exploited null-dereference checks to introduce simple affine types in C++. Cppcheck also checks for null-dereferences. Unfortunately, that approach means that borrow-counting references have a larger sizeof than non-borrow counting references, so optimizing the count away potentially changes the semantics of a program which introduces a whole new way of writing subtly wrong code.

Meta/Facebook are long time OCaml users, their logo is on the OCaml website. Their static analysis tool and its predecessor are both written in OCaml.

CISA Director Easterly's comments about cyber security. Agree or disagree?
Then this idea that the US government will tell tech companies how to write secure software. Let's get this straight, the private sector, especially big tech is miles ahead of US government in this regard. Microsoft literally invented threat modelling and modern exploit mitigations. Facebook has the best appsec processes pretty much in the whole world, including their own cutting edge code analyzer. AWS uses formal verification everywhere. Meanwhile the US government itself runs mission-critical systems that's almost literally held together by bubble gum and toothpicks. Maybe they could dial down the arrogance a tad, get their own shit together, learn how this cyber stuff is actually done and only then try lecturing everyone else.

A quick look at free C++ static analysis tools
I notice there isn't fbinfer. It's pretty cool, and is used for this library.

"Move fast, break stuff" is a great approach when you aren't pushing the broken bits to production. Fuck, even Facebook, the big "move fast, break stuff" company, uses tools to detect errors in its continuous integration toolchain. https://fbinfer.com/

Beyond Functional Programming: The Verse Programming Language (Epic Games' new language with Simon Peyton Jones)
TBH, there's a non-zero amount of non-"ivory tower" tools you may have used that are written in functional languages. Say, Pandoc or Shellcheck are written in Haskell; Infer and Flow are written in OCaml. RabbitMQ and Whatsapp are implemented in Erlang (FB Messenger was too, originally; they switched to the C++ servers later). Twitter backend is (or was, at least) written in Scala.
What are some alternatives?

SonarQube - Continuous Inspection
HHVM - A virtual machine for executing programs written in Hack.
Spotbugs - SpotBugs is FindBugs' successor. A tool for static analysis to look for bugs in Java code.
workflow-kotlin - A Swift and Kotlin library for making composable state machines, and UIs driven by those state machines.
Error Prone - Catch common Java mistakes as compile-time errors

Checkstyle - Checkstyle is a development tool to help programmers write Java code that adheres to a coding standard. By default it supports the Google Java Style Guide and Sun Code Conventions, but is highly configurable. It can be invoked with an ANT task and a command line program.
