tutuca's runtime in Wax, compiled to wasm-gc: the components below are written in Wax (components/) and compiled to component modules the page loads at run time, and every click goes from the DOM through the wasm module's event routing, a transaction on the root, and a morph of the DOM.
Write your own, or edit these, in the playground: it compiles a component's .tcd and .wax in the browser and mounts it.
