Object.freeze()与const [英] Object.freeze() vs const

问题描述

Object.freeze() 似乎就像过渡便利方法要在ES6中使用const一样.

在某些情况下两者都在代码中占据了位置吗?还是有一种首选的方式来处理不可变数据?

Are there cases where both take their place in the code or is there a preferred way to work with immutable data?

我应该使用 Object.freeze() 直到我使用的所有浏览器都支持const的那一刻，然后切换为使用const?

Should I use Object.freeze() until the moment all browsers I work with support const then switch to using const instead?

推荐答案

const和Object.freeze是两个完全不同的东西.

const and Object.freeze are two completely different things.

const适用于绑定(变量").它会创建一个不可变的绑定，即您不能为该绑定分配新的值.

const applies to bindings ("variables"). It creates an immutable binding, i.e. you cannot assign a new value to the binding.

Object.freeze适用于值，更具体地说，适用于对象值.它使对象不可变，即您无法更改其属性.

Object.freeze works on values, and more specifically, object values. It makes an object immutable, i.e. you cannot change its properties.
