Are there any important differences between declaring <script type="text/javascript"> </script> and <script language="javascript"> </script>?
(Note I'm not asking about these declarations vs. the blank "<script>" tag)

scripttype. Specifies the type of the script. Some common values: A JavaScript MIME type like: application/javascript (default) or application/ecmascript.
The HTML <script> type Attribute is used to specify the MIME type of script and identify the content of the Tag. It has a Default value which is “text/javascript”. Syntax: <script type="media_type"> Attribute Values: It contains a single value i.e media_type which specifies the MIME type of script.
The <script> HTML element is used to embed executable code or data; this is typically used to embed or refer to JavaScript code. The <script> element can also be used with other languages, such as WebGL's GLSL shader programming language and JSON.
async: It is used to specify the script is executed asynchronously. charset: It is used to specify the character encoding used in an external script file. defer: It is used to specify that the script is executed when the page has finished parsing. src: It is used to specify the URL of an external script file.
Use <script type="text/javascript"> or simply <script> (if omitted, the type is the same). Do not use <script language="JavaScript">; the language attribute is deprecated.

The language attribute was used when <script> was introduced in HTML 3.2 and took a language name (such as JavaScript). The type attribute replaced it in HTML 4.0 (as everything describing non-HTML media started taking MIME types) and takes a MIME type (such as text/javascript). More recently it also supports the special value module for JavaScript modules (which support the import keyword).
