How to use the <script> tag in HTML

The <script> tag is used to define a client-side script, such as a JavaScript. It can be used to execute JavaScript code within an HTML document.

To include JavaScript code in an HTML document, you can either write the code directly within the <script> tag or link to an external script file. Here's an example of both methods:

Example of inline script:

<script>
    document.getElementById("demo").innerHTML = "Hello, World!";
</script>

Example of linking to an external script file:

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

In the first example, the JavaScript code is written directly within the <script> tag. In the second example, the script is linked to an external file called myscript.js.

Main attributes of the <script> tag:

Attribute	Description
src	Specifies the URL of an external script file.
type	Specifies the MIME type of the script. Default value is "text/javascript".
async	Specifies that the script is executed asynchronously (only for external scripts).
defer	Specifies that the script is executed after the document has been parsed (only for external scripts).

Here's an example of an external script file with the src attribute:

<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

In this example, the jQuery library is loaded from an external URL using the src attribute.

Remember to always include the closing tag </script> at the end of the script code.
