Here you have two DatePickers built with react-toolbox-core. Same component logic, different styles. Left is web, right React Native 🤘

Github was acquired by one of the companies with more contributors to crucial open source projects like Node or Webpack. The same company that brought you VS Code, Powershell and Typescript and open sourced Chakra. This is not necessarily bad, don't be fucking assholes.
