Jetpack uses Babel by default, because:
- this way you get JSX support out of the box
- you can be sure that the code you write will run in all the browsers you support
Jetpack uses the following Babel plugins and presets:
@babel/plugin-syntax-dynamic-import@babel/preset-env@babel/preset-react
See lib/webpack.js.js for the exact configuration.
It's easy to extend Babel with extra plugins or plugins by using .babelrc file.
