Our First JavaScript Programming
Let’s write our first JavaScript Program.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Ginktage.com Home Page</title>
<script language="javascript" type="text/javascript">
document.write('Welcome to Ginktage.com JavaScript Tutorial');
</script>
</head>
<body>
</body>
</html>
The above displays a simple text using the document.write method which is used to write a string to the HTML page. Below is the output of the above HTML code.
