将babel polyfill添加到React Native Project [英] Add babel polyfill to React Native Project

问题描述

我在android上遇到问题.收到此错误:

I´m having a issue on android. Got this error:

未定义不是函数(评估'_iterator2typeof Symbol ==='function'?Symbol.iterator:'@@ iterator'´)

undefined is not a function(evaluating '_iterator2typeof Symbol==='function'?Symbol.iterator:'@@iterator'´)

我认为这与for for es6的使用有关.

I think it is related to the use of for of, es6.

我可以将babel-polyfill添加到React Native Project吗?

Can i add babel-polyfill to React Native Project ?

推荐答案

为了添加 babel-在安装

In order to add babel-polyfill to your react-native project after installing

npm install --save babel-polyfill

只需在您的输入端点中将其导入:

just import it like this in your entry endpoint:

import 'babel-polyfill';

现在，您可以使用新的内置函数，例如Promise或WeakMap，静态方法(例如Array.from)和实例方法(例如Array.prototype.includes等)

Now you can use new built-ins like Promise or WeakMap, static methods like Array.from and instance methods like Array.prototype.includes, etc.
