babel 7如何正确连接polyfill？

Question

如何正确连接Polyfill？我阅读了Babel 7的所有文档并遵循了它。在下面可以看到我的设置。如果我将其添加到webpack配置中

entry: [
    'core-js/stable',
    'regenerator-runtime/runtime',
    './main.js'
],

然后一切正常。但根据文档，此行可以删除，因为babel.config.js中的所有设置]

如果我从此行中删除，则Redux存储在IE11中不起作用

babel.config.js

module.exports = function (api) {
    api.cache(true);

    return {
        presets: [
            [
                '@babel/preset-env',
                {
                    debug: true,
                    useBuiltIns: 'entry',
                    corejs: {
                        version: '3.6',
                        proposals: false
                    },
                }
            ],
            '@babel/preset-react',
            'rsuite'
        ],
        plugins: [
            'react-hot-loader/babel',

                {
                    corejs: {
                        version: 3,
                        proposals: true
                    }

如何正确连接Polyfill？我阅读了Babel 7的所有文档并遵循了它。在下面可以看到我的设置。如果我在webpack配置条目中添加此代码：['core-js / stable'，'...

Answer 1

我认为这是由于反应不支持ie10的事实。我在未定义的ie10中设置和在ie11中未加载redux存储时出错。根据文档，反应需要全局导入polyfill。https://reactjs.org/docs/javascript-environment-requirements.html

Answer 2

仅不要删除为polyfill添加的这些行
