Better $.ajax() requests — using new jqXHR promises and deferred objects

betterajax1.js

$.ajax({
    data: someData,
    dataType: 'json',
    url: '/path/to/script'
}).done(function(data) {
    // If successful
   console.log(data);
}).fail(function(jqXHR, textStatus, errorThrown) {
    // If fail
    console.log(textStatus + ': ' + errorThrown);
});
