I’ve been asking myself, what is the difference between this tag:

<script language="javascript">

and this tag:

<script type="text/javascript">

After doing some googling, I found this documentation.

The “language” specifies the scripting language of the contents of this element. Its value is an identifier for the language, but since these identifiers are not standard, this attribute has been deprecated in favor of type.

Therefore, you can say goodbye to <script language="">
