The rise of JavaScript has seen the rise of so-called web applications, also called web apps or sometimes single-page web apps. The distinction between a web page and a web app is somewhat fuzzy. In general, web apps do not follow earlier patterns of interaction with the web server. The user is typically on the same web page for long periods of time, even though the display may change as they interact with the page. Rather than having the web browser generate HTTP requests and reload the page, JavaScript code is used to interact with the server in the background and update the display as needed.
