ES6 动态类名 [英] ES6 Dynamic class names

问题描述

我一直在试验 ES6 类，想知道您是否可以动态更改类名?例如

I have been experimenting with ES6 classes and am wondering if you can change class names dynamically? For example

class [Some dynamic name] {}; 

推荐答案

对于您想要实现的任何目标，可能都有更好的解决方案，但您可以将类表达式分配给对象:

There is probably a better solution for whatever you are trying to achieve, but you can assign a class expression to an object:

let classes = {};
classes[someName] = class { ... };

这在 ES2015 中并没有真正改变:如果你想创建一个动态命名的绑定，你必须使用一个对象或其他一些映射来代替.

This didn't really change in ES2015: if you want to create a dynamically named binding, you have to use an object or some other mapping instead.
