The observer pattern is used to enable a one-to-many dependency between objects so that when one object changes state, all its dependents are notified and updated automatically.

It's called House (MD). It'll of course be open source. It's clocking in at ~5kb of compressed JavaScript (no ts, sorry, not sorry!). Here's a taste from the work-in-progress prototype:

TypeScript was inspired by a strange ask from the outlook team. Anders Hejlsberg(Anders Hejlsberg) - creator of C#, TypeScript, Turbo Pascal & Delphi - tells us how TypeScript was born: “The world started building larger and larger applications in JavaScript. We saw that externally, but also internally. One of the trigger events was when the outlook team came to see the C# team and asked us whether we would pretty please productize this thing called Script#. And we go, well, what is Script#? It's this cross compiler that allows you to cross compile C# into JavaScript such that you can basically treat JavaScript as an instruction language and run your C# apps in a browser. Why would anyone want to do that? Well, because then you can get a grownup programming language with grownup tooling. You can use Visual Studio, you can have projects. You can do all of these wonderful things that you can't do with JavaScript because JavaScript is just the scripting language with shitty tooling. And we thought, well, perhaps a better approach would be to fix JavaScript. I mean, surely you're not going to be best of breed in the JavaScript ecosystem by telling people to write in a different programming language”

"CSS scroll-driven scroll-snapping animations" by Giana Just a ten out of ten absolutely gorgeous example of using these new APIs. Not a line of JavaScript in sight (except a polyfill to make it work more places).

this is one of the most common problems on react sites, but it's solvable with less than 10 lines of javascript you can see how what i type gets wiped out after hydration, but if you use an inline script tag like shown in this demo your input seamlessly transitions
