Q

How does window.alert() handle the order of execution in JavaScript?

A). It executes after all other statements in the script. B). It executes before other statements in the script. C). It executes in parallel with other statements in the script. D). It executes based on user interactions with the webpage.

Answer & Solution

Answer: Option Option A

Solution:

window.alert() handles the order of execution in JavaScript by executing after all other statements in the script. When window.alert() is encountered in the script, it pauses the execution flow and displays the alert dialog box to the user, halting the script until the user dismisses the alert. After the alert is closed, the script continues its execution from the next statement after the window.alert() statement. This behavior ensures that alert messages are displayed at the appropriate time in the script's execution flow and do not interrupt other script functionalities or statements.
