Q
Which method can be used to display a confirmation dialog box in JavaScript?

Answer & Solution

Answer: Option Option B
Solution:
The method used to display a confirmation dialog box in JavaScript is window.confirm(). This method creates a dialog box with a message, an OK button, and a Cancel button, allowing the user to confirm or cancel an action. Unlike window.alert(), which only displays an OK button for acknowledging a message, window.confirm() provides options for user interaction and decision-making through the confirmation dialog box.
