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.

An intro to TSConfig for JavaScript Developers
target - Specifies the ECMAScript target version for the emitted JavaScript. Defaults to ES3. To ensure maximum compatibility, set this to the lowest version that your code requires to run. ESNext setting allows you to target the latest supported proposed features.

TC39

Pipeline Operator great again!
Current Status: You'd have to check the TC39 proposals repository or the official proposal text for the most recent status. As of my last update, it had not yet reached Stage 4 (final stage) of the TC39 process, which means it wasn't part of the ECMAScript specification yet.

Updates from the 89th TC39 meeting
There were a couple of other proposals that made stage 1 too, can see here.

Don't make me think, or why I switched to Rails from JavaScript SPAs
The working group most in charge of JS is ECMA's TC-39 (TC => Technical Committee) [0]. They've been taking a very deliberate, slow path to expanding the "standard" library because they take a very serious view of backwards compatibility on the web. Some proposals were shifted because of conflicts with ancient versions of things like MooTools still out in the wild, for instance. (This was the so-called "Smooshgate" incident [1].)
This may speed up a bit if the Built-In Modules proposal [2] passes, which would add a deliberate `import` URL for standard modules which would give a cleaner expansion point for new standard libraries over adding more global variables or further expanding the base prototypes (Object.prototype, Array.prototype, etc) in ways that increasingly likely have backwards compatibility issues.
TC-39 works all of their proposals in the open on Github [3] and it can be a fascinating process to watch if you are interested in the language's future direction.

Ask HN: Where are the resources for complex architectures for Node.js?
My biggest pointer would be to remember that Java & JavaScript aren't named that way by coincidence. They're two different approaches to a similar problem. Java suffers from Enterprise Development (eg: Enterprise FizzBuzz[0]), JavaScript suffers from Ultimate Accessibility (eg: how many questions on Stack Overflow conflated jQuery and JS?).
> How should exceptions be managed? [...] Has there been a debate about best practice? Where can I find it?
I suggest you handle the errors you can and otherwise let it crash.[1][2] Debates in NodeJS-land have steered towards more monadic/Result-like structures and working synchronous-looking try/catch onto async/await. NodeJS and its various components are open source, you'll have a lot of luck looking around on GH for issues & PRs related to a feature -- same for the language, ECMAScript[3] officially.[4]
Since you mentioned Clojure, have you looked at ClojureScript?[5] That may be a good entry to JS authors & articles you'd enjoy.
> I have the impression that NodeJS is a bit more magical than the JVM [...] Is that correct? Where are good resources on this subject?
As other replies have mentioned, you're really talking about V8[6] for the "JSVM" executing that code. A thing I've seen throw some people for a loop is how minimalist the specification actually is.[7] The magic in NodeJS is certainly from V8 and the rate of optimizations there but also libuv,[8] what actually powers the infamous event loop.
Hope that helps!

[7]: "ECMAScript as defined here is not intended to be computationally self-sufficient; indeed, there are no provisions in this specification for input of external data or output of computed results. Instead, it is expected that the computational environment of an ECMAScript program will provide not only the objects and other facilities described in this specification but also certain environment-specific objects, whose description and behaviour are beyond the scope of this specification except to indicate that they may provide certain properties that can be accessed and certain functions that can be called from an ECMAScript program." https://tc39.es/ecma262/#sec-overview

The OpenD Programming Language (fork of D)
The reference compiler, DMD, is open source: https://github.com/dlang/dmd
But they don't accept just any Pull Request or features the community submits, understandably. There's a process called DIP for language improvements: https://github.com/dlang/DIPs/blob/master/DIPs/README.md
However, by some accounts, it's really hard to get anything through.
Given D already has so many feature, I find that to be a good thing , to be honest, by not everyone agrees, of course.

Mojo 🔥: A programming language for all AI developers
Borrow checking does not require lifetime annotations. D is a precedent there. Look at DIP25 and DIP1000.

Carbon Language: An experimental successor to C++
There's no "nogc" containers in phobos, or allocators, or an idiomatic way to do safe manual memory management. It expects you to do it the C way. It's also impossible to implement some things because of how D does moving. There's a DIP in the works to change how moving works, but it's overly complicated and bound to introduce even more bugs. https://github.com/dlang/DIPs/blob/master/DIPs/DIP1040.md
-
Is there any other programming language aside from C++ that has move semantics feature available?
D Is drafting up move semantics to interface better with C++. Although they're going a bit the Rust way in the current proposal. D has tried a couple of other strategies, but unique pointers and C++ interoperability kind of forced the hand of Walter Bright.
