[Beta] Using the structuredClone() for updating a nested object

https://beta.reactjs.org/learn/updating-objects-in-state#updating-a-nested-object

I think that deep cloning object with structuredClone() and putting the clone into setPerson() is better solution for the problem than using the spread operator.

The the example that was provided can easily be changed this way:

personCopy = structuredClone(person);
personCopy.artwork.city = "New Delhi";
setPerson(personCopy);

This can help avoiding the mistake when spread operator is used to deep clone objects. See example below:

const original = { a: { b: 1 } };
const falseCopy = { ...original };

falseCopy.a.b = 2;

console.log(falseCopy); // logs {a: {b: 2}}
console.log(original); // also logs {a: {b: 2}}

I am sorry if I have failed to follow contributing guidelines. I am aware that the second example is not the best representation of my point.

從連結的 React 文件章節「Updating a nested object」開始，並結合 structuredClone() 提案檢視目前使用展開運算子的範例。完成的標準是：該章節清楚呈現所選擇的更新方式，並避免讓讀者誤解淺層複製與深層複製的差異。
