What is "$" in Chrome console? -
when type $ in chrome console returns function. sure it's not jquery's $.
if want use jquery in console, best way trigger jquery in chrome console $.
$ alias document.queryselector. in same vein there $$ alias document.queryselectorall.
it defined in command line (console) api.
command line api reference
the command line api contains collection of convenience functions performing common tasks: selecting , inspecting dom elements, displaying data in readable format, stopping , starting profiler, , monitoring dom events.
if have $ defined on page global (perhaps using jquery), you'll global, not command-line built-in.
there other handy functions defined there.
to run jquery, without having in page source code, may find chrome extensions handy, or copy-paste jquery source code in console.
