js循环生成对象

// 假设我们要创建一个包含10个用户对象的数组
const users = [];
for (let i = 0; i < 10; i++) {
  users.push({
    id: i + 1,
    name: `User${i + 1}`,
    email: `user${i + 1}@example.com`
  });
}
console.log(users);

const userCount = 10;
const users = Array.from({ length: userCount }, (_, index) => ({
  id: index + 1,
  name: `User${index + 1}`,
  email: `user${index + 1}@example.com`
}));
console.log(users);

const users = [];
for (let i = 0; i < 10; i++) {
  // 使用let声明i，确保每次循环都有独立的作用域
  users.push((function(index) {
    return {
      id: index + 1,
      name: `User${index + 1}`,
      email: `user${index + 1}@example.com`
    };
  })(i));
}
console.log(users);

const users = [];
for (let i = 0; i < 10; i++) {
  users.push({
    id: i + 1,
    name: `User${i + 1}`,
    email: `user${i + 1}@example.com`,
    greet: () => `Hello, I'm ${this.name}` // 注意：这里的this可能不会指向预期的对象
  });
}
console.log(users);
