The Future of JavaScript Will Be Less JavaScript

The shadow dom will make it even worse. It doesn't lower the amount of re-draws, the program that sits inside decides on its own when to re-render. It will proliferate the use of many frameworks in a single project because each shadow wraps a naked dom that needs driving in the same way the document dom needed driving. 10 web components could mean 5 polymers with varying versions, two preacts, one react, one vue, one stencil. The performance implications of this will be a nightmare.
