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.

Differences between TypeScript and Elm
Elm compiler performance was measured after the release of version 0.19 that contained several performance improvements. The expected approximate times for 50,000 lines of Elm code are 3 seconds for a build from scratch and 0.4 seconds for an incremental build. The actual compile time for the incremental build is around 100 milliseconds. The other 300 milliseconds are used to write the output to a file.

Ezno
Thank you. Just checked out the Bagel post (https://www.brandons.me/blog/the-bagel-language) and it looks really cool. Identifying pure functions (whether that is by syntax annotation or from synthesis) is a really good idea, gives me some ideas for doing function inlining in Ezno. I like the "Misc niceties" section, a few of those may of may not be on Ezno's todo list :)
The automatic / inferred generic restrictions is quite cool. https://hegel.js.org/ got there before me! Basic restriction modification is quite simple e.g. `(x) => Math.sin(x)`, x wants to be a number so can add that restriction. It gets more difficult with higher poly types. `(someObj) => Math.sin(someObj.prop1.prop2)` requires modifying not just `someObj` but a property on a property on it. And `(x, y) => printString(x + y)` requires doing even more complex things. But its definitely possible!

The TypeScript Experience
Can TypeScript be improved in this respect? Or, in broader terms, can a superset of JavaScript support a sound type system without becoming overly complicated?
-
Differences between TypeScript and Elm
An alternative to TypeScript can be Flow, a library maintained by Facebook. Flow, similarly to TypeScript, is not a sound type system. "Flow tries to be as sound and complete as possible. But because JavaScript was not designed around a type system, Flow sometimes has to make a tradeoff". Another alternative is Hegel, a type system that "attempts" to be sound. It is unclear to me if the attempt succeeded or not but it is worth checking.

An introduction to type programming in TypeScript – zhenghao
Check out Hegel[0], it uses Flow syntax, it's compatible w/ .d.ts type definitions and has a smarter type inference model than both TS and Flow IMHO.
