Q

When is it recommended to use document.write() in JavaScript?

A). After the document has finished loading. B). Before the closing </body> tag. C). Before the document has finished loading. D). Within the <head> section.

Answer & Solution

Answer: Option Option C

Solution:

It is recommended to use document.write() before the document has finished loading, typically within the <head> section or early in the <body> section. Using document.write() after the document has loaded can lead to issues such as overwriting the entire document's content or causing delays in content rendering. Placing it before the closing </body> tag is also acceptable for dynamically generating content during page load.
