can you use embedded ruby in custom javascript files in rails?

Question

How does one embed ruby code in javascript for rails? I know you can do this easily in javascript responders for action methods (for e.g. in create.erb.js). But is there a way to do this for other custom javascript files that are included in the application using javascript_include_tag?

For e.g. in create.erb.js I can write code such as <%= if current_user_name ="xyz" %>

Is there a way to have this type of embedding in a custom js file such as custom.js that is used across the application and not just for generating a response for format.js.

Thanks,

I had a similar question open earlier but people pointed out that it was too open-ended. I made changes to the question to incorporate the feedback but it was closed out by then. So, please read the content before thinking that it is a duplicate. — Tabrez

You can just create an _application.js.erb file (name it whatever you wish) in the views/shared folder and then include it in your application's layout file.

<%= render '/shared/application.js' %>

Make sure you wrap it in script tags like normal and ensure that you use the DOM ready wrapper within that JS file like you normally would as well.
