Q

How does document.write() handle JavaScript code execution within written content?

A). It executes JavaScript code within written content. B). It ignores JavaScript code within written content. C). It triggers an error if JavaScript code is included. D). It converts JavaScript code into plain text.

Answer & Solution

Answer: Option Option A

Solution:

document.write() handles JavaScript code execution within written content by allowing JavaScript code to be executed directly as part of the content. This enables developers to include dynamic JavaScript functionalities, calculations, or interactions within the written content, enhancing the interactivity and functionality of the webpage. However, developers should ensure that the included JavaScript code is valid and properly integrated with the surrounding content to avoid errors or unexpected behavior.
