function addNumbers(num1, num2) {
  return num1 + num2;
}

console.log(addNumbers(5, 10)); // 输出 15

var numbers = [5, 10, 15, 20];

var sum = numbers.reduce(function(total, num) {
  return total + num;
}, 0);

console.log(sum); // 输出 50

var person = {
  name: 'John',
  age: 30,
  city: 'New York'
};

console.log(person.name); // 输出 'John'
console.log(person.age); // 输出 30
console.log(person.city); // 输出 'New York'

var numbers = [5, 10, 15, 20];
var [num1, num2, num3, num4] = numbers;

console.log(num1); // 输出 5
console.log(num2); // 输出 10
console.log(num3); // 输出 15
console.log(num4); // 输出 20

var person = {
  name: 'John',
  age: 30,
  city: 'New York'
};
var { name, age, city } = person;

console.log(name); // 输出 'John'
console.log(age); // 输出 30
console.log(city); // 输出 'New York'
