How nginx returns a piece of js that can be executed on the client

Question

I want to use nginx configuration to automatically return a piece of js when accessing a certain URL, such as alert("some message")

I want to achieve this through the following configuration

location /foo {
          default_type application/javascript;
          return 200 '<script>alert("hello");</script>';
 }

But the actual access in the browser only returns text

<script>alert("hello");</script>

No dialog box pops up. Can nginx support returning js? How to configure it correctly?
