How do you include JavaScript in an HTML document?

Including JavaScript in an HTML document is done using the <script> tag. This tag is specifically designed to embed or reference JavaScript code within an HTML document. When the browser encounters the <script> tag, it processes the code contained within it or referred to by the src attribute.

For example, you can include JavaScript directly within your HTML document by placing it between opening and closing <script> tags:

<script>

console.log("Hello, World!");

</script>

Alternatively, you can link to an external JavaScript file by using the src attribute:

<script src="script.js"></script>

This flexibility allows developers to either write inline scripts or link to external scripts, promoting clean and maintainable code.

Other tags mentioned in the options do not serve the purpose of incorporating JavaScript into HTML. The <javascript> and <js> tags do not exist in HTML specifications, and using the <include> tag is not a standard way to include scripts in HTML. Therefore, the use of the <script> tag is the correct and standard method for including JavaScript in HTML documents.
