ES6是否支持{a as a1} = obj这样的扩展语法，或者是否存在RFC？

Question

请考虑以下代码段

const x = {
     name: 'somebody'
};

const { name as somePerson } = x;  // Would be awesome to have something like this

Answer 1

您可以更改Object Property Assignment Pattern [You Don't Know JS: ES6 & Beyond, Chapter 2: Syntax]中的目标：

  

此处的句法模式为source: target（或value: variable-alias）。

{ name: somePerson }

const x = {
     name: 'somebody'
};

const { name: somePerson } = x;

console.log(somePerson);
