This example demonstrates how a single-page application skeleton is transformed from a static document into an interactive, AJAX-driven experience. The visualization shows a list of user-submitted code entries, with each entry dynamically loaded and rendered without a full page refresh. The implementation uses jQuery’s `$.ajax` method to fetch the `lucky_ajax.md` file and other resources, then updates the DOM with the retrieved content. The code also relies on JavaScript’s `Promise` API for handling asynchronous responses, and highlights the use of `XMLHttpRequest` for network communication. The data source is the downloaded application skeleton, whose structure is revealed through the fetched files. The example focuses on the interaction between client-side scripting and server responses.
