var person = {
firstName: 'John',
lastName: 'Doe',
age: 30,
isStudent: false,
greet: function() {
console.log('Hello, I am ' + this.firstName + ' ' + this.lastName);
}
print_name() {
console.log(lastName + ' ' + firstName)
}
};
如何使用对象
console.log(person.firstName); // 输出: John
person.greet(); // 输出: Hello, I am John Doe
javascript中的类(class)是用于创建对象的模板，和c++中的类相似，但是需要在constructor()函数中声明类成员
class User {
constructor(name) {
this.name = name;
}
greet() {
console.log("Hello, I'm " + this.name)
}
}
使用方法
var user = new User("Alice")
user.greet()
