> The only valid value, to this day, is "text/javascript". Other script types have been supported for a while. Some compile-to-javascript languages can be setup to use script tags in their language. For example, CoffeeScript can be setup[1] to compile <script type="text/coffeescript"> tags at runtime. Also, WebGL can load shaders[2] from script tags of type "x-shader/x-vertex" and "x-shader/x-fragment".
