alerts pros and cons

Alerts can be very helpful in letting users know that an action has been completed. However, alerts can also be distracting or irritating when they are used too frequently or provided in instances where it is already clear what action has occurred.

Do an Internet search on the pros and cons of alert boxes and possible alternatives. Share your opinion on alert boxes. Would you use them on a website? Why or why not? Be sure to provide rationale and support for your opinion.
