There's an eslint plugin for extracting JS from HTML, so you can catch issues even when using inline JS! https://github.com/BenoitZugmeyer/eslint-plugin-html

Today I learnt that you can mix HTML inline in markdown! For example, the following is valid.
Foo <hr/>
I'd assumed that you needed HTML separately, like ``` blocks, but no: https://spec.commonmark.org/0.31.2/#raw-html
Admittedly HTML is very restricted on most sites, but it's helpful for SSGs.
Coming from JS or Python, imports in Rust feel weird. They're entirely optional aliases for fully qualified symbols, which are always available.
I don't know of many other languages where you can just start using libraries. Java is the only one I can think of.
One interesting consequence of the rise of LLMs: there's more demand for tools that handle untrusted input.
Arbitrary HTML+JS can be safely run in a browser. Lean can check an arbitrary proof.
These work really well with an LLM that can be wrong, but sometimes gives exactly what you want. Are there other tools in this family?
