[create-react-app version 2.0](https://reactjs.org/blog/2018/10/01/create-react-app-v2.html) added a lot of new features. One of the new features is upgrading to [Babel Version 7](https://babeljs.io/blog/2018/08/27/7.0.0#jsx-fragment-support), which enables the Short Syntax of [React Fragments](https://reactjs.org/docs/fragments.html#short-syntax). Fragments have been a feature of React since version 16.2, but the Short Syntax hasn’t been available since Babel 7.0. Fragments let you wrap a group of children without adding an extra node to the DOM, which is helpful if you need a specific DOM structure.
