在 q 中是否有内置函数来配置比赛？

Question

q JavaScript 库中是否有配置比赛的内置函数？

示例：

function fnThatReturnsAPromise1() { /*...*/ }
function fnThatReturnsAPromise2() { /*...*/ }

//Pseudocode: I want to have the first one of these functions that resolves, be the result
q.race([fnThatReturnsAPromise1,fnThatReturnsAPromise2])
.then(function(resultOfWinner) {
  // ...
});

编辑：源代码中似乎有一个 race 方法，但文档中没有提及。 https://github.com/kriskowal/q/blob/v1/q.js#L738

自从 v0.9.7 there is a Q.race method that does exactly what you want. It's still not documented yet in the API reference 虽然。

此外，由于 v1.0.1 the function is available as .race on the ES6-compliant Q.Promise 对象。

Is there a built-in function to configure a race in q?
