Q
How can you prevent script execution until the user interacts with an alert dialog box created by window.alert()?

Answer & Solution

Answer: Option Option B
Solution:
You can prevent script execution until the user interacts with an alert dialog box created by window.alert() by placing the alert method within an asynchronous function. This approach allows the script to continue executing other statements while waiting for the user's response to the alert. Using the await keyword, defer attribute, or executing the alert method inside a loop does not guarantee the same behavior and may not be suitable or effective for pausing script execution until the alert is dismissed.
