JavaScript 语法:{Ci, CC} 是什么? [英] What is this JavaScript syntax: {Ci, CC}?

问题描述

我正在做一些 FF 插件开发，我看到这样的语法:

I'm doing some FF add-on development and I'm seeing syntax like this:

var {Cc, Ci} = require('chrome');

只是好奇那个语法是什么，以及它是否对 FF 开发或其他东西很特殊.

Just curious what that syntax is and if it's special to FF development or something else.

推荐答案

参见 Domenic 的回答，了解什么是解构赋值的语法.下面的答案就是为什么 FF 插件开发需要这样做.

See Domenic's answer as to what the syntax is which is called a destructuring assignment. The answer that follows is why this is needed for FF add-on development.
