The required type attribute specifies the MIME of the script type.

The type attribute identifies the content between the <script> and </script> tags.

MIME types consist of two parts: media type and subtype. For JavaScript, the MIME type is "text/javascript".

Both the type and language attributes can be used to specify the type of script in the <script> tag. </script>

The language attribute has been criticized in the HTML and XHTML standards, which promote the use of the type attribute. Unfortunately, the values ​​of these two properties are not the same.

If you are using JavaScript, you can use the following two attributes:

language = "JavaScript"

type = "text/javascript"

You may occasionally see the value of language as VBScript (for type is text/vbscript), indicating that the included script code is written in Microsoft's Visual Basic Script.

With JavaScript, you can also use the language value "JavaScript 1.1" to indicate that the included script statements can only be processed by Netscape 3.0 or later. Netscape 2.0 only supports JavaScript 1.0 and cannot handle scripts marked "JavaScript 1.1".
