转自:http://blog.vjeux.com/2011/javascript/how-prototypal-inheritance-really-works.html Everywhere on the web we read that Javascript has prototypal inheritance. However Javascript only provides by default a specific case of prototypal inheritance with thenewoperator. Therefore, most of the explanation...
Understanding JavaScript inheritance mechanics is important, even if you don't plan to use JavaScript OOP patterns, since many of language built-in functionality based on inheritance. I am not advocating of using OOP patterns and "classical"-like inheritance in JavaScript at all. I personally prefe...
To understand how prototypes are used for inheritance, see the MDN articleInheritance and the prototype chain. Example In the following, a new instance ofEmployeeis created, then tested to show that its__proto__is the same object as its constructor'sprototype. ...

To understand how prototypes are used for inheritance, see the MDN articleInheritance and the prototype chain. 当一个对象被创建时,它的__proto__属性和内部属性[[Prototype]]指向了相同的对象(也就是它的构造函数的prototype属性).改变__proto__属性的值同时也会改变内部属性[[Prototype]]的值,除非该对象...
Real Prototypal Inheritance in Javascript The Javascript specifications only gives us the new operator to work with. However, Douglas Crockford found a way to exploit the new operator to do real Prototypal Inheritance! He wrote the Object.create...

Saying that public fields participate in prototype inheritance is misleading and suggestive that they may be assigned to the prototype like public class methods are. Removing this line helps prevent that confusion. It will also helpfully correct AI responses which are saying public fields are defined...
