 Create React App doesn’t support decorator syntax at the moment because:
 
 * It is an experimental proposal and is subject to change.
 * The current specification version is not officially supported by Babel.
 * If the specification changes, we won’t be able to write a codemod because we don’t use them internally at Facebook.
