document.write() deleting all existing HTML
I am studying javascript now.(I am a beginner).
It says "Using document.write() after an HTML document is fully loaded, will delete all existing HTML"
When I run this code, I see the following result.
How come I still see existing html? ("My First Web Page" inside <h1> tag and <p> tag)

@Stefan Hoffman,

Note: as document.write writes to the document stream, calling document.write on a closed (loaded) document automatically calls document.open, which will clear the document.
