Project mention: Apple Notes Expected to Gain Markdown Support in iOS 26 | news.ycombinator.com | 2025-06-04

True: https://godbolt.org/#g:!((g:!((g:!((h:codeEditor,i:(filename... but I understood hoten to be saying that compilers would generally produce that version from the short-circuiting version, and they don't.

Project mention: Ask HN: Thoughts on wasp-JS, a full-stack framework for node | news.ycombinator.com | 2025-07-20
Exploring, less verbose web-frameworks for my codegen product.
Anyone used wasp-js in production?
They claim a lot of things, but wanted to make sure it can handle workers and async jobs.
https://github.com/wasp-lang/wasp
Could only find three case-studies of actual deployment on their site. Hopefully the founders will respond.

It is reportedly used on websites like Langfuse and Million.dev.

mitosis
Write components once, run everywhere. Compiles to React, Vue, Qwik, Solid, Angular, Svelte, and more.
I explored libraries like Valtio and Mitosis, but neither fit perfectly. I didnāt want to add a peer dependency for Valtio, and Mitosis didnāt work well with a shared context.

If you still think a polymorphic component would be better, really can't deal with plain HTML, or donāt want to write CSS in a separate file (though I am not sure why), my next suggestion would be to take a look at PandaCSS and create custom patterns or explore other options like vanilla-extract. In my opinion, these tools are an over-engineered CSS metalanguage but still better than a polymorphic component.

A programming language for the cloud āļø A unified programming model, combining infrastructure and runtime code into one language ā”

This is super cool. I have been using TypeScript To Lua (https://github.com/TypeScriptToLua/TypeScriptToLua) for a little game side project and it works quite well, I am pleased with it. It does end up generating a lot of Lua code though because it has to support all of TypeScriptās features, which isnāt ideal. Iād expect Tealās output to be much more concise Lua which has me interested.

JSON is simple and flexible, but has no typing information. Sure it is possible to join a JSON schema file, but that needs to be taken care of and checked. Ex, with additional tooling like typescript-json-schema or ts-json-schema-generator.
