Definition and Usage
The write() method writes HTML expressions or JavaScript code to a document.
The write() method is mostly used for testing: If it is used after an HTML document is fully loaded, it will delete all existing HTML.
Note: When this method is not used for testing, it is often used to write some text to an output stream opened by the document.open() method. See "More Examples" below.
Tip: The document.writeln() method is similar to write(), only it adds a newline character after each statement.

Example
Using document.write() after an HTML document is fully loaded, will delete all existing HTML.
In this example we illustrate what happens when we put document.write() inside a function. When the function is invoked, all HTML elements will be overwritten and replaced with the new, specified text:
// This should be avoided:
function myFunction() {
document.write("Hello
World!");
}

</pre>
<p>Note that writeln() add a new line after each statement:</p>
