The syntax to add internal JavaScript is:

<SCRIPT>
JavaScript code
.....
</SCRIPT>
<HEAD>
OR
<BODY>
<SCRIPT>
JavaScript code
.....
</SCRIPT>
</BODY>
External JavaScript
JavaScript code can be written in a file and saved with the .js extension and this file can then be
linked inside the <head> and </head> tags of the HTML document in which we want to add this
code. The SRC attribute of the <script> tag allows to give path of the JavaScript file. The syntax to
add external JavaScript is:
<HEAD>
<SCRIPT TYPE="text/javascript" SRC="D:\first.js">
</SCRIPT>
</HEAD>
Note that there are many other scripting languages, hence, it is recommended to use the TYPE
attribute with the <SCRIPT> tag and set its value to text/javascript to specify that scripting
language we are using.

Similar to HTML5 web page, we can use any text editor like Notepad, Visual Studio Code, Sublime
Text, etc. to create JavaScript programs. After typing the JavaScript code, any web browser like
Google Chrome, Firefox, Microsoft Edge, etc. are used to view the web page. Let us create a web
page using internal JavaScript.
Follow the given steps to create JavaScript program:
Step 1 Type <script type = “text/javascript”> between the <HEAD> and </HEAD> tags to use
JavaScript.
Step 2 Use the alert( ) method to display virtual alert box that contains some specified message
and an OK button.
