Which JavaScript method shows a modal alert message to the user?

• A. Alert
• B. Prompt
• C. Log
• D. Confirm

Answer: (A)

Browser modal messages are shown with the alert() function. It pops up a dialog that displays the given message and an OK button, and it stops code execution until the user dismisses it. This is why it’s the one that specifically shows a modal alert message to the user. The prompt() function asks the user to input text before continuing, so it’s for gathering data rather than just notifying. The confirm() function asks the user to confirm an action with OK or Cancel, returning a boolean. There isn’t a standard Log function for displaying a modal dialog; logging to the console uses console.log and doesn’t interrupt the page.
