I think we can implment JavaScriptResult ourselves since it is not supported officially. It is easy:

public class JavaScriptResult : ContentResult
{
    public JavaScriptResult(string script)
    {
        this.Content = script;
        this.ContentType = "application/javascript";
    }
}

This can be achieved by returning ContentResult MSDN 

return Content("<script language='javascript' type='text/javascript'>alert('Hello world!');</script>");

or other way would be making use of ajax

return json(new {message="hello"});  

 $.ajax({
        url: URL,
        type: "POST",
        success: function(data){alert(data.message)},    
    });

Currently ASP.NET MVC 6 doesn't support JavaScriptResult like in MVC 5. An interesting discussion for this can be found here (there's some solutions for your problem too): https://github.com/aspnet/Mvc/issues/2953

Personally I think that sending JS code to the client is a bad thing (send the client the data that the JS needs and then perform the functions invocations there) but it seems that there's a valid situation for this (look at the last comment).
