React Js Detect user switches tabs or leaves the page
React Js Detect user switches tabs or leaves the page:In React.js, you can detect when a user switches tabs or leaves the page by utilizing the
visibilitychange event provided by the Document Object Model (DOM). By attaching an event listener to the visibilitychange event, you can trigger specific actions when the visibility state changes. For example, you can pause or stop ongoing processes, display a warning message, or save the user's progress.This event is fired when the user switches tabs, minimizes the window, or switches to a different application. Handling this event effectively allows you to provide a better user experience and maintain application state accordingly.
