来这里问的好处是可以避免使用 Baidu，毕竟这里还是有人用 Google 的（逃）

Wikipedia: Object-based

In computer science, the term object-based has two different senses:

A somehow limited version of object-oriented programming, where one or more of the following restrictions applies: (a) There is no implicit inheritance, (b) there is no polymorphism, (c) only a very reduced subset of the available values are objects (typically the GUI components).

Prototype-based systems (that is, those based on "prototype" objects that are not instances of any class).

简要翻译下：

在计算机科学当中，基于对象一词有两种不同含义

• 满足至少其一：没有明确的继承、没有多态、对象的使用只局限在很小的范围内

• 基于原型而不是类的实例构建对象

补充一下：

在 ES2015 之前，Javascript 只能基于对象（参见 http://stackoverflow.com/a/6954346/3291805）

现在 ES2015 可以真正面向对象了（明确的继承）

class Base {
    foo(bar = '') {
        console.log('foo' + bar);
    }
}

class Example extends Base {
    constructor() {
        super();
        
        this.bar = 'bar';
    }
    foo() {
        super.foo(this.bar);
    }
}

new Base().foo(); // foo
new Example().foo(); // foobar
