Here are some examples demonstrating the usage of QueryX:
queryX('div').addClass('highlight');
queryX('.container').append('<div class="new-element">New Element</div>');
queryX('input').attr('disabled', true);
queryX('button').on('click', function() {
queryX(this).toggleClass('active');
});
queryX('.parent').children();
queryX('.element').closest('.container');
var formData = queryX('form').serialize();
console.log(formData);
