var _ = require(\'underscore\')

As far as I know Node.js engine "requires/charges" a module/file.js in a different scope (I don't know exactly how), for security reasons (imagine a module could change the variables were it's required. That would be dangerous! More information about this concern: Information hiding).

The only exception are global Node.js objects that are exposed into the module scope.

A global object is, precisely the object "global", and everything you define without var keyword actually is added to that global object:

foo_var = "Whatever"

means that:

console.log(global.foo_var) // Logs "Whatever"
