What is the use of script in html
<script> tag is used to define client-side scripts, such as JavaScript. The </script>
<script> element can either contain script statements or point to an external script file through the "src" attribute. </script>
JavaScript is commonly used for image manipulation, form validation, and dynamic content changes.
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>
</html>Output results:
