Babel Preset does not provide support on IE11 for Object.assign - “Object doesn't support property or method 'assign'”

Question

I am using babel-preset-env version - 1.6.1 for my react app, i am getting a error on IE :- Object doesn\'t support property or method \'assign\'

Answer 1

You need Babel Polyfill.

Either import it in your entry JS file, or use Webpack.

import "babel-polyfill";

or in webpack.config.js

module.exports = {
  entry: ["babel-polyfill", "./app/main"]
}

NOTE : babel-polyfill Should be imported on very top else It will not work
