JavaScript – JavaScript in Head and Body Tag

JavaScript in Head and Body

JavaScript can be written inside the both <head> section and <body> section. Sometimes we need to write the JavaScript code in both sections to better understand or calling the different functions.

While writing JavaScript code <head> and <body> section we have to use <script> tag for both.

Here you can see an example where I have written JavaScript code in two ways by putting inside the <head> section and by putting inside the <body> section. These two are the formal ways to write scripting code.

I always put in the body section of the HTML document because It will help to load the page faster.

HTML / JS Code

<html>
 <head>
        <script type="text/javascript">
   function book(){
    alert ("JavaScript is Awesome");
   }
     </script>
     </head>
    <body>
     <script type="text/javascript">
    document.write("Leave it!! No need to develop.");
  </script>
        <input type="button" onClick="book()" value="DEVELOP">
    </body>   
</html>
