使用Prototype扩展本机对象不好吗？ [英] Is using Prototype to extend native objects bad?

问题描述

我在某处读到了使用 prototype 来扩展本机对象（ String ， Number ，数组等）是一个坏主意。这是真的？为什么或为什么不呢？

I read somewhere that using prototype to extend native objects (String, Number, Array, etc.) was a bad idea. Is this true? Why or why not?

推荐答案

我认为这不好。如果您看一下Ruby on Rails，很多本地对象都会使用自定义功能进行扩展，这是一个非常好的框架。

I don't think it's bad. If you have a look at Ruby on Rails, very many native objects are extended with custom functionality and it's a very good framework.

如果你更改本机对象上的现有方法。这可能会导致不可预见的后果。

What would be bad is if you change existing methods on native objects. this could cause unforseen consequences.
