5. need to invoke “alert” somehow…. window[“alert”] will do… we need a reference to the window…
6. rumor is sort() will return the window when used out of context…
7. same idea with window[“alert”], but we can assign the method to a variable prior to invoking it to make it out of context, which makes it return the window for whatever reason… _=[][“sort”] _() == “DOMWindow”
8. getting close, we now have the sort which gives us a reference to the window, we also know how to invoke alert as a property like key, now we just need some text to alert….
