Dynamically generated Javascript, CSS in ASP.NET MVC

ASP.NET allows to generate HTML dynamically using server tags (razor or ASPX). But Is there any good way to generate *.js or *.css content the same way, other than using inline(embedded) CSS/Javascript. Nowadays with technologies like Ajax more and more logic moves from server-side to client side in Javascript. It would be great to have that opportunity to generate JS dynamically using all flexibility that ASP.NET provides for HTML generation.
