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.

Forth: The programming language that writes itself: The Web Page
My first programming languages were x86 assembly and Forth. My Dad was into Forth, and I learned programming from him. I wrote several x86 Forth systems for DOS as a teenager, culminating in a somewhat-polished ANS compatible one I called "Third": https://github.com/benhoyt/third -- it's kind of amazing being able to have a fully bootstrapped Forth compiler (including an assembler) in a couple thousand lines of code.
Just the other day I transcribed an old article I had co-written for the Forth Dimensions magazine. I still like the ideas in Forth, but the stack manipulation quickly gets tedious and is very hard to read. Just look at the code examples in https://benhoyt.com/writings/forth-lookup-tables/ -- especially Search-Table. Yikes! Yes, naming things is hard, but apparently not naming them is even harder.

Lookup Tables: article I co-authored for “Forth Dimensions” as a teen
I just finished transcribing this from the scanned PDF, and thought it might be interesting to others. It certainly took me back! I was really into Forth as a teenager, and wrote several of my own Forth compilers [1]. It's a unique and interesting language, though most Forthers spend too much time writing their own compilers and being language zealots instead of getting things done. It's hard to believe anyone could think the Search-Table code in "Figure Five" is sane. There's more stack-effect tracking than code!

Byte Magazine: The FORTH programming language
My dad, who was a minister by day and Forth hacker by night, got me into programming when I was a teenager, and Forth and x86 assembly were my first languages. I wrote a small self-hosting Forth compiler for 8086 DOS (https://github.com/benhoyt/third), a tiny 32-bit Forth operating system for the 386 (I guess you'd call it "bare metal" today). Incidentally, my brother used my Third compiler at his work for a few years to write test scripts for embedded systems.
I still love the simplicity of Forth, and the fact that you can get a full Forth system going in a few KB on a new microcontroller. I learned the basics of assemblers, bootstrapped compilers (though not parsers, because Forth doesn't need a "real" parser), recursion, how to implement control structures, various kinds of bytecode (called "threaded code" in the Forth world), linked lists, hash tables, and so on. I also dislike 3rd party dependencies to this day (Forth has a pretty extreme not-invented here culture).
I was really intrigued by Factor when it came out (https://factorcode.org/), as a modern incarnation of Forth, but I never really used it. By that point I had a "real" programming job and was doing absurd things like writing CGI scripts in C, until I discovered Python in the early 2000's. I stuck with Python for many years and really liked it, though more recently I've moved to Go.
I learned a lot by playing with Forth as a teenager, and I'm really grateful for the language. It was an amazing way to start programming.

My history with Forth, and stack machines
My impression so far is (in general), Forth are practically limited to doing embedded/microcontroller development.
For us, web/mobile/desktop app devs, beside:
- 8th (https://8th-dev.com)
- Factor (https://factorcode.org)
Any suggestion which implementation we should look for?
- Forth: The programming language that writes itself: The Web Page
- Retro: A Modern, Pragmatic Forth

Pharo 11, the pure object-oriented language and environment is released!
Factor is also very much worth a look. Forth-style syntax, but with many of the ideas from CL and Smalltalk as well. In fact as a CL fan, I was very impressed by it. It's also quite "batteries included" a la Python.

The toki pona of programming.
Otherwise, and more seriously, I'm not completely sure variables are needed. Factor is quite usable (it's my favorite go-to language if I quickly need to script something), and mostly doesn't have them.

A Dynamic Forth Compiler for WebAssembly
There's a note on the page from 2022-08-19, that a lot has been added to it. It also links to the github page[1] for the up-to-date changes.
I am a Lisp, April, APL/J/BQE, and Forth[2] aficionado. I did some file munging programs in Factor back in 2012 at my job to sort through theater attendance logs in Word to compile statistics.

What the hell is Forth? (2019)
Is there any "battery-included" ANS Forth (more or less like Python/Go) which provides access to concurrency, networking, database, GUI, etc?
Not an embedded device programmer, but mostly deals with frontend apps, and occasionally backend, so those are very relevant to me.
Or perhaps use "non-traditional" Forths like 8th (https://8th-dev.com) or Factor (https://factorcode.org)?
