A pop-up window works by using JavaScript or a similar scripting language to literally 'pop up' a new browser window in front of the current webpage. This window can be triggered automatically when a page loads, or as a result of an action taken by the user, such as clicking a link. Pop-up windows are often used for advertisements, notifications, or to display additional information without leaving the current page. However, due to their intrusive nature, many web browsers now come with built-in pop-up blockers to restrict them.
