<%= javascript_include_tag "blah.js", :defer => "defer" %>
This will get you (in development):
这将使您（在开发中）：
<script defer="defer" src="/assets/blah.js" type="text/javascript"></script>

You can also do
你也可以这样做
<%= javascript_include_tag "blah.js", defer: true %>
which is more consistent with other switches.
这与其他开关更一致。
