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.

TypeScript is now officially 10 years old
Probably because it compiles them to a pre-standard ES5-compatible implementation based on good ol' `Foo.prototype`. And since they've already handled them one way, they can't become spec-compliant without breaking backwards compatibility.
The other place where this shines through particularly egregiously is the support of ESM static import/export. Everybody's build tools been compiling that back down to CJS so hard that Node.js 16+ introduced intentional incompatibilities between CJS and ESM modes just to get people to finally switch to the standards-compliant module system. So you end up in a situation where the library is written in TypeScript with ESM syntax but the only available browser build is a CJS blob which completely defeats the main touted benefit of static imports/exports, namely dead code elimination...
So you decide what the hell, let's switch TSC to ESM and moduleResolution node16, and end up having to use something like https://github.com/antongolub/tsc-esm-fix because the only allowed fix for TSC doing the wrong thing is at the completely wrong level - https://www.typescriptlang.org/docs/handbook/esm-node.html - if you don't see what's wrong with that, you're one of today's lucky 10000...

[AskJS] Kicking a dead horse - TS vs JS
I particularly like this thread in the TC39 types proposal. TypeScript IS a development trojan horse and locks you into the Microsoft Way of being a JS developer.

HTML First – Six principles for building simple, maintainable, web software
Edit: There is a proposal to extend JavaScript with type annotations, which would allow ("a reasonably large subset") of TypeScript to run directly in the browser. Yay!

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.

Show HN: Conway's Game of Life in TypeScript's type system
this is exactly what I want from the _Types as Comments_ proposal[0] as I think it's the only way that types can feasibly become part of the language. It's hard to imagine how all of the concepts TS introduces via special syntax can be covered otherwise.

Why Htmx Does Not Have a Build Step
Crossing my fingers that the proposal for allowing (browser-ignored) type annotations in javascript progresses: https://tc39.es/proposal-type-annotations/
Between that, HTTP2/3 and ES modules many of the downsides for building apps with no compile step are almost completely mitigated.

TypeScript Without Transpilation
JSDoc can get you pretty far, but it can be clumsy sometimes. There’s a [TC39 proposal](https://github.com/tc39/proposal-type-annotations) to allow types to live in JS code and be treated as comments (similar with Python types today)
- Do you think typescript will ever have native support on brosers? Or we will have only the JS type annotations?
