UI Deploy

Open your favorite web application, even a simple TodoMVC would work. Let it load. Change some data, for example add a new item to the list. Now reload the page. What happens? The page goes blank, then some initial markup appears. Then all of the sudden, everything shifts - the application's code took over, rewriting the page's tree structure, forcing the browser to render the loaded data. Here is one example: the screen recording of Angular2 TodoMVC application where I add items and reload the page.
