To close a window opened as a popup in JavaScript, you first need to have a reference to that window. Typically, this is achieved when opening the window using `window.open()`. Here's a quick solution: 1. Open a popup window: `let myWindow = window.open('', '', 'width=200,height=100');` 2. Close the popup: `myWindow.close();` Remember, for the close method to work, the script must have created the window. Also, browser security settings may prevent certain actions, so ensure your use case aligns with user interaction guidelines.
