how would an example of javascript without implicit global variables work? For example, how does it get access to "Array", "require" or "window" ?

(I don't think "use strict" goes to the length of turning javascript into bracha's newspeak but I may likely have no idea what "strict javascript" actually refer to)

You can access global variables as normal, but you can't implicitly declare them by doing `myGlobaVar = 5` - you have to use `window.myGlobalVar`.
