在对象销毁分配中转义保留的关键字 [英] Escape reserved keywords in object destructing assignment

问题描述

是否可以在销毁对象的分配中使用保留关键字.

Is it possible to use reserved keywords in an object destructing assignment.

具体地说，我正在尝试使用名为default的属性处理JSON.

Specifically I am trying to handle JSON with property property named default.

//Doesn't compile
class FooBar {
  constructor({foo, default}) {
    this.foo = foo;
    this.default = default;
  }
}

/* json from server {foo: "bar", default: true} */
new FooBar(json);

推荐答案

可以将它们用作属性名称，但不能用作变量名称.选择其他目标:

It's possible to use them as a property name, but not as a variable name. Choose a different target:

class FooBar {
  constructor({foo, default: def}) {
    this.foo = foo;
    this.default = def;
  }
}
