Tips and Notes

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

Tip: This element is useful for users who have disabled scripting in their browser or whose browser does not support client-side scripting.

Note: There are multiple ways to execute external scripts:

If async="async": The script executes asynchronously relative to the rest of the page (the script will execute while the page continues to parse is executed) If async is not used and defer="defer": the script will be executed when the page has finished parsing. If neither async nor defer is used: the script is read and executed immediately before the browser continues to parse the page

Examples are as follows:

<html>
<head> 
<meta charset="utf-8"> 
<title>123</title> 
</head>
<body>
<script>
document.write("Hello World!")
</script> 
</body>
