Web components can be built separately to the rest of an application as standalone components and included by adding a <script> tag, and then using them is as straightforward as using an HTML tag. You need a build process for the component (or the author of the component does..) but you don't need one for the website you're using it in. You can do that with a React component as well but you don't get the benefits of things like styled components if you do. You do with web components.
