A popup window in JavaScript is a new browser window that opens when triggered by a user's action, such as clicking a button. Using the `window.open()` function, developers can create these additional windows to display information, gather input, or provide interactive functionality separate from the main webpage. These windows can be customized in terms of size, position, and features (like scroll bars), making them versatile tools for enhancing user experience on websites.
