Natural sort order has been promoted as being more human-friendly ("natural") than machine-oriented, pure alphabetical sort order. For example, in alphabetical sorting, "z11" would be sorted before "z2" because the "1" in the first string is sorted as smaller than "2", while in natural...

除了维护自己的一组属性外,JavaScript 对象还继承另一个对象的属性,称为其“原型”。对象的方法通常是继承的属性,这种“原型继承”是 JavaScript 的一个关键特性。 JavaScript 对象是动态的——属性通常可以添加和删除——但它们可以用来模拟静态类型语言的静态对象和“结构”。它们也可以被用来(通过忽略字符串到值映射...
