Here the $ sign can be replaced with the keyword "jQuery".

$.functionName();

coincides with

jQuery.functionName();

if you are using jQuery framework. If you use something else, it can refer to the underlying object, as in jQuery.

$is just the name of some object. It can be jQuery or Prototype if you use one of these libraries.

So, it $.functionName()simply means calling a function with the name of an functionNameobject with a name $.
