这个打字稿语法是什么？

Question

Stumbled upon this code: 偶然发现这段代码：

const { operator } = this;

What does it mean? 这是什么意思？

Answer 1

It's object destructuring . 这是对象的解构。 This 这个

const { operator, other } = this;

is equivalent to 相当于

const operator = this.operator;
const other = this.other;

It's borrowed from ES6, which has the same feature . 它是从ES6借来的，它具有相同的功能。
