To add a script, use the <script> tag. The HTML <script> tag is used for declaring a script (such as JavaScript) within your HTML document.
The script tag supports the following additional attributes −
| Attribute | Value | Description |
|---|---|---|
async  | sync | Specifies that the script is executed asynchronously |
| Charset | charset | Defines the character encoding that the script uses. |
| defer | defer | Declares that the script will not generate any content. Therefore, the browser/user agent can continue parsing and rendering the rest of the page. |
| src | URL | Specifies a URI/URL of an external script. |
| type | text/JavaScript application/ecmascript application/JavaScript text/vbscript | Specifies the scripting language as a content-type (MIME type). |
| xml:space | preserve | Deprecated − Whether the whitespace in code should be preserved |
