Promise、Promise/A 和 Promise/A+ 之间的区别

Difference between Promise, Promise/A and Promise/A+

我已经阅读了 Promise/A+ 规范,但据我了解还有 Promise/A 和 Promise 之类的东西。它们之间有什么区别? Promise 和 Promise/A 规范也是如此吗?如果是这样,有什么区别?对不起,如果这个问题很愚蠢,因为我是主要的后端开发人员。

提前致谢!

Is Promise a specification as well?

没有。这只是一个具有上下文相关含义的术语。有关可能的定义,请参见 What are the differences between Deferred, Promise and Future in JavaScript? or the Wikipedia entry on the topic 示例。

Is Promise/A a specification as well?

是:http://wiki.commonjs.org/wiki/Promises/A

为什么命名为A?因为还有other approaches

I've read the Promise/A+ specification. What is the difference between them?
