  • why promise?
    • 异步编程为js带来强大灵活性的同时,也带来了嵌套回调的问题。详细来说主要有两点,第一嵌套太深代码可读性太差,第二并行逻辑必须串行执行。
    • 新的ES6中引入了Promise,目的是让回调更为优雅。层层嵌套的回调会让javascript失去美感和可读性,同时javascript也推荐采用链式的方式去书写函数调用。
  • PromiseA+规范
    • A promise represents the eventual result of an asynchronous operation.
    • The primary way of interacting with a promise is through its then method, which registers callbacks to receive either a promise’s eventual value or the reason why the promise cannot be fulfilled.跟promise交互的主要方式是通过他的then方法来注册回调函数去接收promise的最终结果值或者是promise不能完成的原因。
