Exercise

Refactor jQuery code following best practices.

// Good practices
$(document).ready(function() {
  // Cache selectors
  var $form = $('#myForm');
  var $submitBtn = $('#submitBtn');
  
  // Use event delegation
  $form.on('submit', function(e) {
    e.preventDefault();
    // Handle form submission
  });
  
  // Use method chaining
  $submitBtn
    .prop('disabled', true)
    .text('Submitting...')
    .addClass('loading');
});
