Don't marshal when you can cast

var loginDto = <Dto.LoginDto> {};
extend(loginDto, req.body); // marshal the req.body dictionary to strongly-typed object

The code above is inefficient, extending is an expensive process. The above could be simply rewritten as:

var loginDto = <Dto.LoginDto> req.body;

Imagine the nodejs code above if done with statically-typed framework such as ASP.NET MVC, the values from Request.Form (same as nodejs's req.body) need to be marshalled to DTO object every time a request is made, a bit inefficient.

You can make something efficient and be efficient (autocomplete support) when coding with TypeScript.
