As already stated, the idea is that you have an object that represents your DOM. When your code makes changes to the DOM, it actually affects the virtual DOM, this allows for lots of quick changes to the vDOM without much overhead, then at some point the vDom is synchronised with the actual DOM. This reduces the overhead between wasm->JS as you don't have to do it as often, it also can improve the performance as DOM changes can be slow.
