Q

Which method should be avoided when using document.write() in JavaScript?

A). Including multiple document.write() statements within one script. B). Encapsulating document.write() within functions. C). Using document.write() to generate dynamic content. D). Executing document.write() before the <body> tag.

Answer & Solution

Answer: Option Option A

Solution:

Including multiple document.write() statements within one script should be avoided when using document.write() in JavaScript. This practice can lead to issues such as overwriting content or causing unexpected behavior due to the execution order of document.write() statements. Instead, encapsulating document.write() within functions or using it strategically before or during the document loading process is recommended for better control and organization of dynamically generated content.
