HTML DOM open() Method
The DOM Open() method in HTML is the combination of the following three steps:
- Opens an output stream to collect the output.
- Collects output from the document.write() or document.writeln() methods.
- Runs the document.close to display the output written to the output stream.

- MIMEtype: It is the type of document, and it is an optional parameter. The default value of this parameter is “text/html”.
