Browser default global $ function

Question

I\'ve noticed that there appears to be a global function called $ in some browsers which is NOT jQuery, but I can\'t seem to find any documentation on it. What is it?

There is no global $ in browsers.

Some browsers provide a $ in the scope of the Console (if there isn't a global one already).

For example Chrome's documentation says:

$(selector) returns the reference to the first DOM element with the specified CSS selector. This function is an alias for the document.querySelector() function.
