Prototype Chain Example. If the engine fails to search, it continues searching in the prototype of obj object and so on until reaching object.prototype. here in the line (*) the property admin.fullname has a getter in the prototype user, so it is called. And in the line (**) the. so if for any reason you wish to see what is available in the prototype chain of a value's immediate ancestor, the __proto__ property could be used for that. inheritance using the prototype chain. The prototype chain mechanism is simple: When you access a property p on object obj, the javascript engine will search this property inside obj object. understanding how the prototype chain works is crucial if you would like to develop performant code while. the hasownproperty method is defined in object.prototype, which can be accessed by bird.prototype, which can then be. In javascript, all functions have a prototype property and all objects have a __proto__ property that. the prototype chain allows one object to use the methods and properties of its prototype objects via the [[prototype]] linkages. You can also use __proto__ to determine which object a value should inherit from.
