[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.

Comienza con la sección vinculada de la documentación de React, “Updating a nested object”, y revisa el ejemplo actual con el operador spread junto con la propuesta de structuredClone(). Se considera terminado cuando la sección presenta claramente el enfoque de actualización elegido y evita inducir a los lectores a error sobre la diferencia entre una copia superficial y una copia profunda.
