javascript - 重新定义 promise

Question

Promise 现在是 es6 中的全局保留字，并且 linters 会抛出错误。那么这样做有什么坑

var Promise = require("bluebird");

或者我应该做什么

var BluebirdPromise = require("bluebird");

Answer 1

只要不是全局的，重新声明 promise 似乎没有问题。但是第二种是更好的方法

Many of us do that. There's no problem. You're just using a faster implementation, that's all. But note that you may use more and more promises given by various libraries, so this is a very limited replacement (there are discussions in the node world about ways to define a library as a global promise provider). – Denys Séguret
