## tag < script > :

## Definition and Usage

The <script> tag is used to define a client-side script, such as a JavaScript.

The <script> element either contains scripting statements, or it points to an external script file through the src attribute.

Common uses for JavaScript are image manipulation, form validation, and dynamic changes of content.

## Tips and Notes

Note: If the "src" attribute is present, the <script> element must be empty.

Tip: Also look at the <noscript> element for users that have disabled scripts in their browser, or have a browser that doesn't support client-side scripting.

Note: There are several ways an external script can be executed:

- If async="async": The script is executed asynchronously with the rest of the page (the script will be executed while the page continues the parsing)
- If async is not present and defer="defer": The script is executed when the page has finished parsing
- If neither async or defer is present: The script is fetched and executed immediately, before the browser continues parsing the page

Example
< html > < head > < /head > < body > < script type = "text/javascript" > document.write ( " This is an Script ... ! " ) < /script > < /body > < /html > | code
| output
