JavaScript 函数参数内的大括号

JavaScript函数参数内的大括号（{}）是一种特殊的语法，用于传递多个参数值，这些参数值被视为一个对象。在函数调用时，我们可以使用大括号来传递键值对，从而更方便地传递和处理多个参数。本文将介绍如何使用大括号作为函数参数，并提供一些示例代码来帮助读者理解。

javascript
function printPersonInfo({ name, age, gender }) {
  console.log(`Name: ${name}`);
  console.log(`Age: ${age}`);
  console.log(`Gender: ${gender}`);
}
const person = {
  name: 'John',
  age: 25,
  gender: 'male'
};
printPersonInfo(person);

Name: John
Age: 25
Gender: male

javascript
function printStudentInfo({ name, age, grade }) {
  console.log(`Name: ${name}`);
  console.log(`Age: ${age}`);
  console.log(`Grade: ${grade}`);
}
const student = {
  name: 'Alice',
  age: 18,
  grade: 'A'
};
printStudentInfo(student);

javascript
function printStudentNameAndGrade({ name, grade }) {
  console.log(`Name: ${name}`);
  console.log(`Grade: ${grade}`);
}
const student = {
  name: 'Bob',
  age: 20,
  grade: 'B'
};
printStudentNameAndGrade(student);
