Use the Created Variables on the Statements in our code?

When Andrew creates a pair of variables to contain the elements we keep targeting,

var $password = $(“#password”);
var $confirmPassword = $(“#confirm_password”);

we can use them in our functions without a problem.

My question is, can't we also use these variables in our statements later on in the code?

For instance, can we change this:

$(“#password”).focus(passwordEvent).keyup(passwordEvent);
$(“#confirm_password”).focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

Into this?

$password.focus(passwordEvent).keyup(passwordEvent);
$confirmPassword.focus(confirmPasswordEvent).keyup(confirmPasswordEvent);

Not really an life-or-death issue, but just curious.

Many thanks,

David

Just watched a few more minutes into the video, and Andrew went right ahead and did exactly what I was asking about.
