CSS jQuery Basics (2014) Creating a Password Confirmation Form Perfect

So in the tutorial, enableSubmitEvent() is called after each "key up" and then again all by itself at the end of the document. What is the purpose of calling it at the end of the document if it is called at each "key up"?

Hi Arvin,

Calling enableSubmitEvent() at the bottom like that will call the function once when the page loads, and as a result will disable the submit button, preventing the user from clicking it before entering in their user name and password.

Would giving the Submit button the disabled property in the HTML, as was shown as an example, and then having the function enable it, work just fine without having to call it on the page load?

Here's what I'm thinking:

function submittable(){
  return validUser && validPass && validConfirm;
function submitter(){
  $submit.prop('enabled', submittable());
