Q

Which scenario is NOT suitable for using document.write() in JavaScript?

A). Creating a login form with validation. B). Generating a personalized greeting message. C). Displaying real-time data from an external API. D). Adding event listeners to form elements.

Answer & Solution

Answer: Option Option A

Solution:

document.write() is not suitable for creating a login form with validation as it does not provide the necessary functionality for form input handling and validation. For creating interactive forms, it is recommended to use form elements and event listeners along with JavaScript functions to handle user input, validate data, and perform actions based on user interactions. document.write() is more suitable for generating dynamic content or outputting messages, data, or HTML elements to the document.
