<!DOCTYPE html>

        <head>
          <title> Title of the document<title>
        </head>
          <body>

		</script>
	<h1>
	It is a file with JavaScript. JavaScript file is linked above
	</h1>
          </body>
      </html>
  1. First, we write <! DOCTYPE html> which we used as an instruction to the web browser about what version of HTML file is written in.
  2. Secondly, the <html> tag is used to indicate the beginning of an HTML document.
  3. As above now <head> tag is used to contain information about web page. In this tag a <title> tag is used which helps us to specify a webpage title. Both <head> and <title> tags are Paired tags. So, both have </head> and </title> ending tags respectively.
  4. Thirdly, <body> tag is used to define the webpage body. All the contents to show on website are written here.
  5. Here, in body tag first we linked the JavaScript file. For linking this file, we create a script tag. Script tag is mostly used to link any JavaScript file but in body tag, not in head like CSS files.
  6. And in JavaScript file, we have to write about the required codes, that we need in html file and after this we have to save the JavaScript file with .js extension. You can save this file in any other folder, at desktop and at same location where your html file is.
  7. Now, the script tag that we create in html, in this we have to write about the source of JavaScript file, that where it is saved, here we have to specify full path with file name and its extension.
  8. And you can also use this script tag anywhere in the body, it’s not mandatory to use a top of page and after this you are able to write your html codes as you do.
  9. At last, the <body> and <html> tags are closed with </body> and </html> respectively.
