                     This approach involves loading the component as an independent script within the initial HTML page load, effectively integrating it into the HTML DOM environment. This method not only reduces the space required by the web application, thereby enhancing its load speed, but also leverages the benefits of distributed loading. By loading distinct components of the web application through separate network requests, we can maximize efficiency. In this instance, the react-adobe-embed component is sourced from a CDN as a separate network request, distinct from the main web application. This effectively allows the web application to load in two concurrent parts, or at least simulates this effect, thanks to the inherent multi-threading capabilities of computer systems.
