Resolving Multiple Promise With Rx.js，有没有更好的方法？

Question

好吧，我正在用 Rx.js 练习一些方法。我写了一段代码来解决多个承诺。只是想知道我是否以正确的方式做这件事，还是有更好的方法（也许更短）？

var urls = ["https://api.github.com/users/manju4ever","https://api.github.com/users"];
var responseList = Rx.Observable
                 .merge(urls.map(eachUrl => 
                                 Rx.Observable.fromPromise($.getJSON(eachUrl))));

responseList.subscribe(response => console.log(response));

Output: Two JSON Objects from github api.

我可能会使用 fromArray + flatMap 代替：

var urls = ["https://api.github.com/users/manju4ever","https://api.github.com/users"];

var responses = Rx.Observable.fromArray(urls)
             //Implicitly handle the promises
             .flatMap(function(url) {
               return $.getJSON(url);
             });

responses.subscribe(function(res) {
  console.log(res);
});
