(HTML) DOM is performant, snappy, and cross browser compatible as never before. One of the reasons why jQuery is becoming irrelevant is that DOM finally works.

But when you need to polyfill an entire browser’s worth of functionality, at some point you need to ask if it’s worth the trouble.

Sure, I ignore that, for the sake of an argument. Hopefully webcomponents will be ready soon in evergreen browsers.

You can still compare idea of React and idea of web components, ignoring everything else, and come to some conclusions.
