<SCRIPT TYPE="text/javascript" SRC="path of the JavaScript file/ File

external JavaScript file to be linked.
In an HTML document, JavaScript can be integrated in three distinct places, which are as follows:
In the body: The script runs as the page loads and the output appears in the HTML content.
In the head (as a function): Scripts are written as functions, which can be called from anywhere
else in the page.
As an external file: JavaScript code can be written in a separate file with a .js extension. This
file is linked to the HTML document using the <SCRIPT> tag.
TYPES OF JAVASCRIPT
In HTML, you can use JavaScript in two ways-internally and externally.
INTERNAL JAVASCRIPT
When JavaScript code is written within the HTML web page then it is called internal JavaScript.
You use the <SCRIPT> and </SCRIPT> tags to place the JavaScript code either in the <HEAD>
or <BODY> tag of the HTML document. The syntax to add internal JavaScript is:
<HEAD> <BODY>
<SCRIPT> <SCRIPT>
JavaScript code JavaScript code
OR
..... .....
</SCRIPT> </SCRIPT>
</HEAD> </BODY>
