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.

[Showcase] My first project in Deno and an early perspective
For reference (for the issues you mentioned): 1. This issue was opened almost immediately to solve the weird .only function not working https://github.com/denoland/deno_std/issues/2979 2. That looks weird to me, will get back to you on this one since it should work I think 3. Generally polluting the global namespace isn't great, but because we're only polluting the namespace of a module (and we choose what parts to import), I personally find it quite freeing. I entirely understand how that might feel awkward. 4. you CAN specifying only writing to certain directories! --allow-write=/path/to/dir would allow that!

Deno v1.27
At least for the ones related to trees, it's just a renaming. Below is a link to the PR. When I initially implemented these trees, I chose the names BSTree and RBTree to keep the names short. I'm guessing the person that proposed renaming them did so to make it more obvious what they are.
https://github.com/denoland/deno_std/pull/2400
The standard library is separate from the runtime. It wouldn't break backward compatibility if you were to update. For example, if you were importing RBTree and upgraded Deno to the latest release, it would keep working just fine. You would only really need to switch to using RedBlackTree instead if there was a change made to it that you wanted.
I think the only time you would need to update your standard module imports to be able to use newer versions of the Deno runtime if the standard module were depending on runtime APIs that have a breaking change.

No Safe Efficient Ways to Do Three-Way String Comparisons in Go
It is like Demo deprecating fs.exists().[1]

Programming language comparison by reimplementing the same transit data app
This was fun to read through.
I would need to profile the code, but the startup time being bad for Deno seems like maybe a combination of the code in here being unoptimized:
https://github.com/denoland/deno_std/blob/0ce558fec1a1beeda3...
(Ex. Lots of temporaries)
And usage of the readFileSync+TextDecoder API instead of readTextFile (which is also a docs issue since it's suggests the first one). It seems the code loads the 100MB into memory, then converts to another 100MB of utf8, then parses with that inefficient csv decoder. The rust and go versions look to be doing stream/incremental processing instead.

Testing frameworks
Sorry to hear that. I want to provide expect API in deno_std in the future: https://github.com/denoland/deno_std/issues/1779

Just migrated my first module from Node to Deno: Froebel - a strictly typed TypeScript utility library.
I just migrated the module to Deno and rewrote the test cases using the Deno test runner. Also contributed a bug fix to the test runner that I encountered during the migration. An npm version is still available and automatically generated from the Deno code via a small bash script (rewriting imports, adding an index.ts, etc.).

Deno.js in Production. Key Takeaways.
Much of Node.js is written in C, yet it's still called Node.js.
Deno has some JavaScript/TypeScript in it. On GitHub https://github.com/denoland/deno is 22.8% JavaScript and 13.2% TypeScript, and https://github.com/denoland/deno_std is 68.2% JavaScript and 31.6% TypeScript.
So to me it's misleading about the name, but not about what Deno is written in.

JEP draft: Exception handling in switch

Project Valhalla: A look inside Java's epic refactor
Nice. So for example, it looks like Kotlin has a nearly identical feature at the language level which will be optimizable when Valhalla ships: https://github.com/Kotlin/KEEP/blob/master/notes/value-class...
> In the future, in a Valhalla-capable JVM, JVM primitive classes will enable efficient representation of Kotlin value classes with an arbitrary number of underlying fields on JVM.

Unchecked Java: Say Goodbye to Checked Exceptions Forever
Most other languages agree that checked exceptions are not good by not having them.
As for alternatives, Try/Result and similar monads have decent adoption even in Java, but personally I quite like the Kotlin philosophy [1] to not have generic error containers and either use runtime exceptions or make failures of the return type.
