'head' is an element in HTML that is accessible to web browser implemented JavaScript via the DOM or Document Object Model.
The head element works as a container for information that is not intended to show on the page itself. The web-page title, referens to css-files or js-files would normally be placed within the head tag, along with SEO metadata.
The head-tag is required for a web page to be semantically valid.

JavaScript files can be created with the extension .js Note that an accompanying HTML file must reference it in order for it to run as JavaScript. You can include the file in your HTML document by adding the following to the head or body of the document: <script type="text/javascript" src="myJavaScriptFile.js"></script> Replace myJavaScriptFile.js with the file name of your JavaScript file.
<html> <head> <script language="JavaScript"> function TriaAngle (base, height) { document.write("the area of the triangle is" +1/2*base*height) } </script></head> <body> <script language ="JavaScript"> var b=(prompt ("enter the base of the triangel")) var h=(prompt ("enter the height of the triangle")) TriaAngel (b,h) </script ></body></html>
