In the Google Chrome JavaScript console, the difference between $$()
and $()
is that $$()
is a shorthand for document.querySelectorAll()
, while $()
is a shorthand for document.querySelector()
.
document.querySelectorAll()
returns a list of elements matching the specified CSS selector, while document.querySelector()
returns the first element that matches the selector.
So, $$('selector')
will return a NodeList of all elements matching the selector, while $('selector')
will return a single Element object for the first matching element.
