JavaScript is a bit confusing for developers experienced in class-based languages (like Java or C++), as it is dynamic and does not provide a class implementation per se (the class keyword is introduced in ES2015, but is syntactical sugar, JavaScript…

Objects have the ability to use data and methods that other objects contain, as long as it lives on the [prototype] chain. In this lesson we’ll test this out by adding properties and working with this linkage of properties. const obj = {firstName: 'T…
原型链(Prototype chain) 原型对象也是普通的对象,并且也有可能有自己的原型,如果一个原型对象的原型不为null的话,我们就称之为原型链(prototype chain). A prototype chain is a finite chain of objects which is used to implemented inheritance and shared properties.原型链是一个由对象组成的有限对象链由于实现继承和共享属性. 想象一个这种情况,2个对象,大部…
