For anyone who is wondering, "functino" is Italian for "tiny function."
Here's another way to write the code, using only a single event handler
(event delegation) instead of individual event handlers on every link. This
will be faster if there are a lot of product descriptions. I'd also put an
ID on the parent DIV - <div class="products" id="products"> - to make it
even faster:
$('#products').click( function( event ) {
var $target = $(event.target);
if( $target.is('a.show-description') ) {
$target.parent().next().show();
return false;
}
});
