9 JavaScript Global Variables
These are the non-standard "global" variables defined on the window object. These can be helpful in identifying possible client-side frameworks and code.
object| oncontentvisibilityautostatechange object| Mozilla object| gaScript function| ga object| webpackChunkclient object| google_tag_data object| gaplugins object| gaGlobal object| gaData3 Cookies
Cookies are little pieces of information stored in the browser of a user. Whenever a user visits the site again, he will also send his cookie values, thus allowing the website to re-identify him even if he changed locations. This is how permanent logins work.
