require an external module when window.shortcut is unavailable
require an external module when window.shortcut is unavailable.
var wrequire = ;var $ = ;var _ = ;var async = ;
The above works correctly, like below.
var $ = window$ || ;var _ = window_ || ;var async = windowasync || ;
window object is not available on node.js environment.
require() function is not available on most web browser environments, either.
wrequire() makes your library ready for both node.js and browsers via browserify etc.
npm install wrequire
