title: Automatic compare check in Angular i18n json files
body: <p>I have 2 files <code>en.json</code> and <code>xx.json</code> with translations in Angular application. Common idea is to create translation in both files for multilanguage application, but sometimes some programmers adding translation just in one of these file, because they testing app only in their language.</p>
  
  <p>I am looking for tool that check same structure in both JSON files, otherwise it throw error and it helps with addition when you creating translations for second language. Do you know any good practices, tools or plugins for this? I am using WebStorm.</p>
