+## Window Confirm Method
+
+You can use the `confirm` method to ask a user to double check a decision on a web page. When you call this method, the browser will display a dialog box with two choices along the lines of "OK" and "Cancel."
+
+For example, say someone has just clicked a Delete button. You could run the following code:
+
+```javascript
+if (window.confirm("Are you sure you want to delete this item?")) {
+  // Delete the item
+}
+```
+
+The message "Are you sure you want to delete this item?" will appear in the dialog box. If the user clicks OK, the confirm method will return `true` and the browser will run the code inside the if statement. If he or she clicks Cancel, the method will return `false` and nothing else will happen. This provides some protection against someone accidentally clicking Delete.
