 The `browserslist` configuration controls the outputted JavaScript so that the emitted code will be compatible with the browsers specified. The `production` list will be used when creating a production build by running the `build` script, and the `development` list will be used when running the `start` script.

-> When editing the `browerslist` config, you may notice that your changes don't get picked up right away. This is due to an [issue in babel-loader](https://github.com/babel/babel-loader/issues/690) not detecting the change in your `package.json`. An easy solution is to delete the `node_modules/.cache` folder and try again.
