Objec.isSealed example is misleading

[nicolo-ribaudo]

let obj = {
  a: 1,
  b: 2,
  c: 3
};

Object.defineProperty(obj, 'a', {
  configurable: false
})

console.log(Object.isSealed(obj)); // false
console.log(Object.isSealed(obj.a)); // true

Initially I thoght that Object.isSealed(obj.a) checked if the a property of obj is not configurable, but it returns true just because obj.a is not an object. A good example would actually seal obj.

EDIT:
Also the description isn't very clear:

Determines if an object or its properties are sealed.

What does it mean that "its properties are sealed"? WDYT about "Determines if the descriptor of its properties can't be changed and new properties can't be created"?

Ah good point, I'll update this. Thanks

This changes all the translations, right?
