类似地,通过new Array()创建的对象使用Array.prototype作为它们的原型,通过new Date()创建的对象使用Date.prototype作为它们的原型。初学 JavaScript 时可能会感到困惑。记住:几乎所有对象都有一个原型,但只有相对较少的对象有一个prototype属性。具有prototype属性的这些对象为所有其他对象定义了原型。 Object.prototype是...
EZArray 的实例表现得像普通数组,我们可以使用继承的方法和属性,比如push()、pop()和length。但我们也可以使用子类中定义的first和last getter。不仅实例方法像pop()被继承了,静态方法像Array.isArray也被继承了。这是 ES6 类语法启用的一个新特性:EZArray()是一个函数,但它继承自Array(): 代码语言:javascript ...

The fetch function retrieves data as JSON array from the provided URL. With forEach, we go through the array. Object.entries(obj).forEach(([key, value]) => { console.log(`${key} ${value}`); }); We go over the entries of each object and print the key and the value to the ...
