[@bs.scope]

bs.scope is used with other attributes like bs.val and bs.module to access "deep" values.

For example:

[@bs.scope "Math"] [@bs.val] external floor: float => int = "";
[@bs.scope ("location", "origin")] [@bs.val] external originLength: string = "length";
[@bs.scope "CONSTANTS"] [@bs.module "MyModule"] external initialDays: int = "";

Js.log(floor(3.4));
Js.log(originLength);
Js.log(initialDays);

compiles to:

var MyModule = require("MyModule");

console.log(Math.floor(3.4));
console.log(location.origin.length);
console.log(MyModule.CONSTANTS.initialDays);

Note: The order of bs.* attributes doesn't matter.
