I always wonder about what sort of js engine such projects use since at the end of the day imo, it is all just a dance b/w js engine, html and css. Html & Css feels a little solved problem but the problem is of the js engine.

Sciter uses quickjs and I just checked and its like 35-36x times slower than V8 JIT

Also another interesting rabbit hole is that I found Duktape in the quickjs benchmarks and I saw https://blogcpp.org/ as one of the projects within Duktape but I can't even see the project on github. We really need some better way of preserving open source stuff I guess

Not some rando's blog engine in C++, or other kinds of stupid throw-away code

Anyway <https://web.archive.org/web/20241122030659/https://github.co...> -> $(fossil clone https://code.rosaelefanten.org/blogcpp) which takes a stunning amount of time but then reports

good callout wrt being slower than JIT. ofc for certain applications it's not a showstopper, ie, if you're not using javascript for your MVC but doing more of a progressive enhancement thing.

CSS2 is closer to trivial, but CSS3 is practically a 3D game engine with all of its matrix transforms, transitions, animations, variables - not to mention all the different layout schemes (Sciter blogged about introducing display:flex and display:grid two months ago)

The most interesting part of Sciter to me is that data persistence goes way beyond localStorage (string key: string value) or filesystem API, instead it's DyBase [0][1] behind the scenes, which looks to be a very intriguing style of storing trees of data in the host language's datatype (including whatever classes you define) without mucking about with the leaky abstractions of an ORM.
