No, it's now officially useless.
不，它现在正式没用了。
The type attribute gives the language of the script or format of the data. If the attribute is present, its value must be a valid MIME type. The charset parameter must not be specified. The default, which is used if the attribute is absent, is "text/javascript".
type 属性给出了脚本的语言或数据的格式。如果该属性存在，则其值必须是有效的 MIME 类型。不得指定字符集参数。如果属性不存在，则使用的默认值是“text/javascript”。
Simply do
简单地做
<script src=yourpath.js></script>
(yes, you can omit the quotes too)
（是的，您也可以省略引号）
Note that you don't have to worry about pre-HTML5 browsers, all of them always considered JavaScript to be the default script language.
请注意，您不必担心 HTML5 之前的浏览器，它们都始终将 JavaScript 视为默认脚本语言。

From the spec:
从规范：
If the language is not that described by "text/javascript", then the type attribute must be present
如果语言不是“text/javascript”描述的语言，则必须存在类型属性
And:
和：
The default, which is used if the attribute is absent, is "text/javascript".
如果属性不存在，则使用的默认值是“text/javascript”。
Conversely, that means that if your srcattribute is for a file that is valid JavaScript, it is not needed.
相反，这意味着如果您的src属性用于有效 JavaScript 的文件，则不需要它。
