如何使用javaScript从函数参数中返回值？

function add(a, b) {
  return a + b;
}

const result = add(3, 5);
console.log(result); // 输出8

function updateName(person, newName) {
  person.name = newName;
  return person;
}

const person = { name: 'Alice' };
const updatedPerson = updateName(person, 'Bob');
console.log(updatedPerson.name); // 输出Bob

function multiplyArrayByTwo(arr) {
  for (let i = 0; i < arr.length; i++) {
    arr[i] *= 2;
  }
  return arr;
}

const numbers = [1, 2, 3, 4];
const multipliedNumbers = multiplyArrayByTwo(numbers);
console.log(multipliedNumbers); // 输出[2, 4, 6, 8]

function calculate(operation, a, b) {
  return operation(a, b);
}

function multiply(a, b) {
  return a * b;
}

const result = calculate(multiply, 3, 5);
console.log(result); // 输出15
