React+antd project runs under ie11: the TypeError: object does not support the "startsWith" property or method

as shown in the figure below, my project is the scaffolding of create-react-app. There is no problem running under ie 9. Running under ie 11 reported the following error.
I went to Baidu, and some people said that I did not quote babel-polyfill, so npm install-- save-dev babel-polyfill,
installed this package in the entry file import "babel-polyfill". I also tried
module.exports = {

entry: ["babel-polyfill", ". / app/js"]

how to make it compatible with ie 11.
