More "Try it Yourself" examples below.

## 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!");
}

## Example

Open an output stream, add some text, then close the output stream:

document.open();
document.write("<h1>Hello World</h1>");
document.close();

## Example

Open a new window called "MsgWindow", and write some text into it:

var myWindow = window.open("", "MsgWindow", "width=200, height=100");
myWindow.document.write("<p>This is 'MsgWindow'. I am 200px wide and 100px tall!</p>");

## Example

Difference between write() and writeln():

<body>
<p>Note that write() does NOT add a new line after each statement:</p>
<pre>
<script>
document.write("Hello World!");
document.write("Have a nice day!");
</script>
</pre>
<p>Note that writeln() add a new line after each statement:</p>
<pre>
<script>
document.writeln("Hello World!");
document.writeln("Have a nice day!");
</script>
</pre>
</body>

## Example
