Prompt Title: Detect Browser Close/Refresh.

Unfortunately, detecting browser close or page refresh using JavaScript is not possible with 100% accuracy on all browsers and devices. However, there are a few methods that can be used to detect these events on most modern browsers.

Here is an example function that uses the beforeunload event to detect when the user is navigating away from the page:

javascriptCopy code
function detectBrowserCloseOrRefresh(callback) {
  window.addEventListener("beforeunload", function (event) {
    event.preventDefault();
    event.returnValue = ""; // Required for Chrome
    callback();
  });
}

This function takes a callback function as an argument, which will be called when the beforeunload event is triggered.

To use this function, you would call it and pass in your desired callback function:

javascriptCopy code
detectBrowserCloseOrRefresh(function () {
  // Do something when the user closes or refreshes the page
});

Keep in mind that this method is not foolproof, as some browsers may not support the beforeunload event, or may provide the user with a dialog box asking them to confirm their intent before leaving the page. Additionally, some browsers may not fire the beforeunload event if the user navigates to a different domain or closes the browser entirely.
