Does Angular Assign Itself To `window.angular` Globally, When Loaded As CommonJS Module?

I'm importing Angular 1.4 in my entry point module of Webpack build as a CommonJS module (i.e. with var angular = require('angular');), but somehow it becomes available in global n

Solution 1:

Angular is strongly tied to global variables, as well as a bunch of other legacy libraries that didn't have a chance to become available as full-grown CJS/UMD modules at some point (and Angular still isn't, as of v1.5.2).

var
...
angular           = window.angular || (window.angular = {})

is equal to

if (!window.angular)
  window.angular = {};

var
...
angular           = window.angular;

The former is several bytes smaller and a couple of dans hackier.
