Polyfilling language features

You can polyfill stable language features not available in your target browsers:

// must be the first line in src/index.js
import 'react-app-polyfill/stable';

// ...

Supporting Internet Explorer

These modules ensure the following language features are present:

1. Promise (for async / await support)
2. window.fetch (a Promise-based way to make web requests in the browser)
3. Object.assign (a helper required for Object Spread, i.e. { ...a, ...b })
4. Symbol (a built-in object used by for...of syntax and friends)
5. Array.from (a built-in static method used by array spread, i.e. [...arr])

You can import the entry point for the minimal version you intend to support to ensure that the minimum language features are present that are required:

// This must be the first line in src/index.js
import 'react-app-polyfill/ie11';
import 'react-app-polyfill/stable';

// ...

or:

// This must be the first line in src/index.js
import 'react-app-polyfill/ie9';
import 'react-app-polyfill/stable';

// ...
