class类的一个问题？

Question

class ExtObject extends Object {

constructor(...args) {

super(...args);

}

}

const obj = new Object({foo:'bar'});

console.log(obj); // { foo: 'bar' }

const ext = new ExtObject({foo:'bar'});

console.log(ext); // ExtObject {}

console.log(ext.foo); // undefined

stackoverflow上面的答案有一条好像是对的，但是英文没看明白。。。还请懂的人说的通俗易懂一点，ExObject
