分解结果并将其赋值给变量

let [a, b, c] = [1, 2, 3];
console.log(a); // 输出: 1
console.log(b); // 输出: 2
console.log(c); // 输出: 3

let { name, age } = { name: 'Alice', age: 25 };
console.log(name); // 输出: Alice
console.log(age);  // 输出: 25

function printPerson({ name, age }) {
    console.log(`Name: ${name}, Age: ${age}`);
}

printPerson({ name: 'Bob', age: 30 }); // 输出: Name: Bob, Age: 30

let [x, y] = [1]; // x 被赋值为 1，y 为 undefined

let [x, y = 0] = [1]; // x 为 1，y 为 0

let data = { user: { name: 'Alice', details: { age: 25 } } };
let { user: { name, details: { age } } } = data;

let { user: { name, details } } = data;
let { age } = details;

let { x = 10, y = 20 } = { x: 5 }; // x 为 5，y 为 20
