What is document write() Method in JavaScript?

The JavaScript document write() method is used to write content (including source codes) to output stream.

This output stream is basically the page that users see!

This means if there’s already a document displayed to users, then calling this method on top of the document will remove the old content and display the new content instead.

For example, using this method we can send a message like “Hello World” to the page.

Or put HTML elements as the argument of this method and they will be rendered on the page.
