Why cant Dollar symbol be used as an alternative fo jQuery in WordPress?

1. Have a look at tip 5 in this web page: 5 Tips for using jquery with wordpress:

   It is important to know that the version of jQuery that comes with
   WordPress automatically calls the jQuery.noConflict(); function, which
   gives control of the $ variable back to whichever library first
   implemented it. If you are loading a different copy of jQuery, you’ll
   need to manually call jQuery.noConflict();, if necessary, from one of
   your JavaScript files.

   I hope that helps.

2. The tricky thing is this particular copy of jQuery is in compatibility
   mode by default. That means that the typical ‘$’ shortcut for jQuery
   doesn’t work, so it doesn’t conflict with any other JavaScript
   libraries that use the dollar sign also, like MooTools or Prototype.

3. jQuery(...) should be used instead of $(...)

   Edit —-
   sorry, i misread your question.
   It depends on the jquery implementation of your wordpress version.
   I have seen wordpress sites that allowed the usage of $ before, but i don’t really know what it depends on.
