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.

CoffeeScript for TypeScript
We often add promising TC39 proposals into Civet so people can experiment without waiting.
We've added https://github.com/tc39/proposal-pipeline-operator, a variant of https://github.com/tc39/proposal-pattern-matching, a variant of https://github.com/tc39/proposal-string-dedent and others.
Since our goal is to be 99% compatible with ES we'll need to accommodate any proposals that become standard and pick up anything TC39 leaves on the table (rest parameters in any position, etc.)

A single developer has been maintaining core.js with little recognition or support. Almost all modern single page apps use core.js. Millions of downloads and hardly any compensation
I was wondering what "dedent" was when I saw this commit since that's what he named the branch. Conveniently, the changelog shows up first in this merge and he Added String.dedent stage 2 proposal which he links. The proposal is a bit dense for me to skim since I'm not particularly familiar with ECMAscript. The code to implement dedent is included and is a bit tricky to skim but if you scroll down to look at what the tests are doing, then the code will hopefully make a bit more sense.

How to use multi line template literals strings in an IDE while keeping indentation in the IDE (vs code)
There's nothing built in that does this yet, but there is a proposal for a String.dedent that would.

Coming to grips with JS: a Rubyist's deep dive
Note, however, that there is a proposal to add pattern matching to JS.

Level up your Typescript game, functionally - Part 2
There's an ECMAScript proposal that is in the works to add this feature to the language! It's going to look something like this.

Building React Components Using Unions in TypeScript
More importantly, TypeScript typically commits to build things into itself when the proposal in JavaScript reaches Stage 3. The pattern matching proposal in JavaScript is Stage 1, but depends on many other proposals as well that may or may not need to be at Stage 3 as well for it to work. This particular proposal is interested on pattern matching on JavaScript Objects and other primitives, just like Python does with it’s native primitives. These are also dynamic types which helps in some areas, but makes it harder than others. Additionally, the JavaScript type annotations proposal needs to possibly account for this. So it’s going to be awhile. Like many years.

Explicit Software Design. Preliminary Conclusions
For true™ functional programming in JS, native pattern matching and partial function application are missing (at least for now: 1, 2). For proper OOP, it lacks real interfaces and compile-time dependency injection.

TypeScript Is Surprisingly OK for Compilers
The proposal for pattern matching syntax seems more akin to what they're looking for.

[AskJS] C# in every Node.js job posting?
There's a proposal to add something like that to JavaScript but it's been stuck in limbo since 2017 although there are libraries like ts-pattern which implement it already.

[AskTS] What do you think will be the future of runtime type checking?
I'll admit, it is easy to assert that the TypeScript language should not be involved in the matters of packages but I also wonder if we're moving towards a point where interfaces will be as common as namespaces and whether or not it would be sensible for the language to incorporate such type assertions into the language formally, after all, it already compiles to various forms of JavaScript and there is a stage 1 proposal submitted to the TC39 committee to give JavaScript pattern matching. If adopted, wouldn't it make sense to allow TypeScript to compile a type into a type guard for the native JavaScript pattern matcher?

Mostly adequate guide to FP (in JavaScript)
Both are active tc39 proposals :)
https://github.com/tc39/proposal-pipeline-operator - Stage 2
https://github.com/tc39/proposal-pattern-matching - Stage 1
Hopefully we get both in the next couple of years.
