What is the best way to declare script tag in HTML5?

Question

I have seen many different ways in declaring script tag. Some of them are:

Variation 1:

 <script type="text/javascript">
     //some javascript here
 </script>

Variation 2:

<script type="text/javascript">
     //<![CDATA[
     // some javascript here
     //]]>
</script>

Variation 3:

 <script language="javascript">
     //some javascript here
 </script>

Variation 4:

       <script>
          //some javascript here
       </script>

There are also other variations as well. When we work in HTML5 + js then which way is more appropriate in declaring Script tag?

Answer 1

In HTML5 you don't need an additional attribute like "type". Just declare JavaScript code with <script></script>.
