If someone could make something like this, https://www.youtube.com/watch?v=dRo_egw7tBc that would be amazing.
In this video @spicyj does a very good job walking through the code from beginning to end, showing what files and folders do what. Even if you don't use react, its worth watching for inspiration.

I know its a big ask, but would be nice to have @metajack or someone do something similar

We should document the relationship between Attr, IDL attributes, content attributes, Element::get_attribute, Element::get_string_attribute, and VirtualMethods::parse_plain_attribute.

I worked a bit on DOM code last week, and immediately ran into the issue that the rooting documentation is out of date. The comments in the source files about how to get from JS to Root were not right.

It would probably be useful to show correspondence from webidl to Rust as well has how to get back and forth between various types.
