深拷贝与浅拷贝的区别

let originalObject = {
  name: "John",
  age: 30,
  hobbies: ["reading", "coding"],
}

//浅拷贝对象
const shallowCopyObj = Object.assign({}, originalObject);

// 修改拷贝对象的属性
shallowCopyObj.name = "Alice";
shallowCopyObj.hobbies.push("painting");

console.log(originalObject);
console.log(shallowCopyObj);
//{ name: 'John', age: 30, hobbies: [ 'reading', 'coding', 'painting' ] }
//{
//  name: 'Alice',
//  age: 30,
//  hobbies: [ 'reading', 'coding', 'painting' ]
//}
