本文探讨了JavaScript作为一种基于原型的语言的特点，区别于传统的类为基础的对象导向语言。JavaScript通过从其他对象创建新对象的方式实现继承，同时介绍了变量作用域及开发者如何通过对象来组织类。
JavaScript is not a real object-oriented language, it is a prototyping language, that is the difference with other object-oriented languages. In Javascript, you don’t use classes, you create objects from other objects.
Because JavaScript is a functionally scoped language creating a function and/or variable which is not wrapped in another function will result in that variable being created in the global scope (window). To combat this, developers place their classes in Objects.
