When i type $ into the javascript console of an HTML document which includes the jQuery Library, the autocompleter gives the following variables: $ (thats clear to me, it transforms something into its jQuery equivalent) $x, $u, $_, $0, $$. The jQuery API gives no results when i search for these variables. They do not even seem to be contained in jquery.js. Do these variables have any relevant meaning?

Edit: OK, i learned, this is not related to jQuery. For the records, what is $$? [duplicate] is not found when searching for "$" or Javascript "$" on Stackoverflow or on Google. Thats why i asked this question.

these are special functions available from the Chrome Command Line, for example;

  • Thanks a lot. These variables do also exist in Firefox. I guess their meaning is the same? – Nils Lindemann Nov 24 '16 at 19:10
  • Yeah, I guess all the browser vendors have their own interpretations/implementations but they end up to be pretty much the same. Makes development a little bit easier again. ;) Good luck! – Lille Hummer Nov 24 '16 at 19:12
