在JavaScript中，继承是一个重要的概念，它允许我们基于现有的类（或构造函数）创建新的类。然而，继承并非没有缺点，它既有优点也有缺点。以下是对JavaScript中继承的优缺点的详细分析：优点：代码复用：通过继承，子类可以复用父类的属性和方法&#x...

JavaScript的类和构造函数

JavaScript的类和构造函数前面一篇博客，我们说到了对象，总结一下就是对象是包含属性和方法的容器。当然说到对象有个问题绕不过，那就是类，当然在es5里边并没有类的概念，但是在这里边有构造函数，可以创建类似于类的函数，说到类我们要知道，类是一种抽象的概念，类似于工厂，模板。然后对象是一具体的一个实例，当然对象可以是类的一个具体实例。接下来接单的说一下“类”和构造函数。 // 对象是....
