                The previous version of this article said React was faster than web components,
                but this only the case if we make the web components render a span. Unlike a React component a web component
                is itself part of the DOM, and so is itself the equivalent of a span. The <em>textcontent</em> strategy exploits this advantage
                to functionally do the same as the React code, and it matches its performance.
