Where should I put

The JavaScript code should be inserted between <script> and </script> tags in HTML. You can place the <script> tags, containing your JavaScript, anywhere within your web page, but it is normally recommended that you should keep it within the <head> tags.

The <script> tag alerts the browser program to start interpreting all the text between these tags as a script.

The script tag takes two important attributes −

  • Language − This attribute specifies what scripting language you are using. Typically, its value will be JavaScript. Although recent versions of HTML (and XHTML, its successor) have phased out the use of this attribute.
  • Type − This attribute is what is now recommended to indicate the scripting language in use and its value should be set to "text/javascript".
  •  Let us take a simple example to print out "Hello World". We added an optional HTML comment that surrounds our JavaScript code. This is to save our code from a browser that does not support JavaScript. The comment ends with a "//-->". Here "//" signifies a comment in JavaScript, so we add that to prevent a browser from reading the end of the HTML comment as a piece of JavaScript code. Next, we call a function document.write which writes a string into our HTML document.
  •  This function can be used to write text, HTML, or both. Take a look at the following code.


      <script language="javascript" type="text/javascript">
            document.write("Hello World!")


Hello World!
