Q
Which of the following is a limitation of using document.write() in JavaScript?

Answer & Solution

Answer: Option Option B
Solution:
A limitation of using document.write() in JavaScript is that it cannot write content after the document has loaded. Attempting to use document.write() after the document has finished loading will not have the desired effect and may lead to issues such as overwriting existing content or causing delays in content rendering. It is recommended to use document.write() during the document loading process or before the closing </body> tag for dynamic content generation.
