Some topics not included by the guide but discussed in the reference include: - ThreadSafety of the VirtualDom - Full usage of `rsx!` and included features - Spread pattern for component properties - Testing - Memoization in Depth - Custom Elements - Custom Renderers ## Contributing If this doc is lacking in any way, is confusing, has a typo, or you'd just like to help improve things, feel free to make a PR against the [Dioxus repo](https://github.com/DioxusLabs/dioxus/tree/master/docs/reference).
