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.

== 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.

|
|
var paragraph = $("p");
|
|
|
|
// ...
|
|
|
|
paragraph = $("p");
