From the article linked:

This attribute indicates the type of script represented. The value of this attribute will be in one of the following categories:

  • Omitted or a JavaScript MIME type: For HTML5-compliant browsers this indicates the script is JavaScript. HTML5 specification urges authors to omit the attribute rather than provide a redundant MIME type. In earlier browsers, this identified the scripting language of the embedded or imported (via the src attribute) code. JavaScript MIME types are listed in the specification.

The attribute was required in earlier versions of HTML, but can be omitted for JavaScript in HTML5. It’s assumed that the script is JS, unless otherwise specified.
