Locality and Wasasbi

Fine, so we have the following code

    Routes.get("/customer',
           basicAuthentication
           {
               log.write("Inline logging dude")
               next()
           },
           {
               response.send(customer)
           }
    )

It's very pretty, I like the way that these blocks fall off each other. Let's compare it to

     app.get('/customer',
           basicAuthentication,
           function(req, res, next) {
             log.write("Logging")
             next()
           },
           function(req, res) {
             res.send(customer)
           }
     )

What's the difference? Well for my money, I prefer the latter because I have req, res and next completely local to the function that is handling that particular step.

Sticking them as "members of the container class" doesn't give you a clear indication of scope or intent, they're further away from the real action and make the code slightly more opaque when you're skimming it over in a monday morning tweet.

Indidentally is this one of the reasons I'm not enjoying Ruby/Rails - lots of methods are springing into existence in the global scope "because", "magic", I prefer the explicit and the local over the magic and distant.

I agree with you in terms of magic. And I favor keeping it to a minimum.
