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...
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...
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. ...
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...

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...
Each constructor is a function that has a property named “prototype” that is used to implement prototype-based inheritance and shared properties. Every object created by a constructor has an implicit reference (called the object's prototype) to the value of its constructor's “prototype” proper...
constructor.prototype, and properties added to an object’s prototype are shared, through inheritance, by all objects sharing the prototype. Alternatively, a new object may be created with an explicitly specified prototype by using the Object.create built-in function. –ECMAScript® 2015 Language ...
