Mojolicious Core Team member Joel Berger discusses some of the features of the recent Mojolicious 9.0 release and how they can improve your web (and async) applications.

Wanting to make use of Ajax is one of the prime reasons for adopting jQuery.

$.get("mydata.txt").then(
                    function (data) {
                     alert(data);
                    },
                    function () {
                     alert("error");
                    })
                   .always(
                    function () {
                     alert("cleanup");
                    });
