Open () Opens the document so that JavaScript can write data to the current location of the document, which is where the JavaScript is inserted. It is usually not necessary to use this method and JavaScript is called automatically when needed.

Write (); Writeln () writes data to the document, which is written as standard document HTML. The difference between writeln () and write () is that writeln () adds a newline after the data is written. This line break is just wrapping in HTML, if it is enough to show the text wrapping, it depends on where the JavaScript is inserted. As in

tag, the line break is also reflected in the document.

Clear () empties the current document.

Close () closes the document and stops writing the data. If you use the WRITE[LN] () or clear () method, be sure to use the close () method to ensure that the changes are displayed.
