在数组中创建客户对象和属性

// 创建客户对象构造函数
function Customer(name, age, gender, contact) {
  this.name = name;
  this.age = age;
  this.gender = gender;
  this.contact = contact;
}

// 创建客户数组
var customers = [];

// 添加客户对象到数组中
customers.push(new Customer("张三", 25, "男", "123456789"));
customers.push(new Customer("李四", 30, "女", "987654321"));
customers.push(new Customer("王五", 35, "男", "567891234"));

// 访问客户对象的属性
console.log(customers[0].name); // 输出：张三
console.log(customers[1].age); // 输出：30
console.log(customers[2].contact); // 输出：567891234
