I would say, to go with the metaphor, that none of our wheels are close to round yet, and every now and again someone invents a new wheel that has a different kind of bump. Concretely, "shadow DOM", reactive (web) components and js frameworks etc. etc. are all ways of trying to get a set of rich UI components (like we're used to from desktop applications) into an environment that was originally built for static text pages, and has been expanded by patchwork ever since. DOM updates are slow and cause flickering because the original model was you submit a form and the entire page reloads; updating part of the page in response to an asynchronous request or a local event wasn't in the original design space, and every solution we've tacked on so far sucks in a slightly different way. Not helped by the complexity of being able to dynamically change the layout and size of every single element - CSS is incredibly powerful, but setting a button to have a 1px border only on hover for example has a tendency to make other page elements "jiggle" in ways you don't want. |
