Make setTimeout in JavaScript support chained operations

The modification is simple, determined by the parameters, and then returns the promise object

(function() {

  var timeout = setTimeout;

  window.setTimeout = function(fn, time) {

    if (!time) {

      time = fn;

      return $.Deferred(function(dfd) {

        timeout(function() {

          dfd.resolvel(dfd);

        }, time);

      }).promise();

    }

    timeout.apply(window, arguments);

  }

})();

call

setTimeout(1000).done(function(dnt) {

  console.log(dnt)

})
