JavaScript:通过计算的键动态解构对象

const { 属性名 } = 对象;

function getUser() {
  return {
    name: 'John',
    age: 30,
    email: 'john@example.com'
  };
}

const { name, age, email } = getUser();
console.log(name); // 输出: John
console.log(age); // 输出: 30
console.log(email); // 输出: john@example.com

const numbers = [1, 2, 3, 4, 5];

for (const number of numbers) {
  console.log(number);
}

const user = {
  name: 'John',
  age: 30,
  email: 'john@example.com'
};

for (const [key, value] of Object.entries(user)) {
  console.log(`${key}: ${value}`);
}
