Javascript Can'；t指定超类中只有getter的属性

今天，我惊奇地发现以下代码错误：

class Base {
  get foo() { return 42 }
}

class Derived extends Base {
  constructor() {
    super()
    console.log(this, Object.getOwnPropertyDescriptor(this, 'foo'))
    this.foo = 52
  }
}

new Derived()

以下是输出：

Derived {} undefined
/Users/andy/clarity/src/server/temp.js:14
    this.foo = 52;
             ^

TypeError: Cannot set property foo of #<Base> which has only a getter
    at new Derived (/Users/andy/clarity/src/server/temp.js:11:5)

很明显，在一次房地产转让中发生的事情比我想象的要多得多。 我想人们认为我应该阅读说明书是对的

const base = {
  get foo() {return 42}
}

const derived = Object.create(base)
derived.foo = 58

console.log(derived.foo) // outputs 42???
