jQuery doesn't cache elements for you. If you've made a selection that you might need to make again, you should save the selection in a variable rather than making the selection repeatedly.
== Noncompliant Code Example
With the default threshold of 2
----
$( "p" ).hide();
$( "p" ).show(); // Noncompliant
----
== Compliant Solution
----
var paragraph = $( "p" );
paragraph.hide();
paragraph.show();
----
== Exceptions
Stored selections are not updated when the DOM changes. Since variables may need to updated this rule ignores selections that are repeated during an assignment.
