title: React-Native: Momentjs - is there a straightforward way how to throw all unused locales from production build
body: <p>I checked my app bundle with <a href="https://github.com/IjzerenHein/react-native-bundle-visualizer" rel="nofollow noreferrer">react-native-bundle-visualizer</a> and found out that locales of momentjs<a href="https://i.stack.imgur.com/IrjOx.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/IrjOx.png" alt="enter image description here"></a> weight almost 400kb. I'm using only English. I found solution for webpack with <a href="https://webpack.js.org/plugins/ignore-plugin/" rel="nofollow noreferrer">ignore-plugin</a>, but solution doesn't look lile RN one. So, if there is one for React-Native?</p>
