2. Method of referencing js external files:

Quote js code in head

<script src=".."  type="text/javascript"></script>

The src attribute specifies the URL of the external script file. Sometimes, we need to run JavaScript in multiple pages of our website. Instead of rewriting the same script, simply create the JavaScript in a separate file, save it with a .js suffix, and reference that file using the src attribute in the <script> tag. Note that external files cannot contain <script> tags! </script>

The type attribute in<script>, the required type attribute specifies the MIME type of the script. </script>

The type attribute identifies the content between the <script> and </script> tags.

Note: HTML code is read and run from top to bottom
