Alert widget
The Magento alert widget implements a modal pop-up window with a confirmation button. It extends the Magento confirmation widget which in turn extends the Magento modal widget.
The alert widget source is <Magento_Ui_module_dir>/view/base/web/js/modal/alert.js.
The widget can be used for implementing alert windows for both Admin and storefront. The design patterns for the pop-up modal windows in the Admin are described in the Magento Admin Pattern Library, the Slide-out Panels, Modal Windows, and Overlays topic.
Initialize the alert widget
The alert widget can be initialized with or without binding to a certain element.
