Q
What happens when window.alert() is executed in a JavaScript code?

Answer & Solution

Answer: Option Option B
Solution:
When window.alert() is executed in a JavaScript code, it displays a modal dialog box with the specified message. This dialog box halts the script execution until the user interacts with it by clicking the OK button, after which the script continues its execution. This behavior makes window.alert() useful for showing important information, warnings, or notifications to users in a way that requires their immediate attention and response.
