title: Translations in JS files with Symfony2
body: <p>I'm currently developing an applications that will need to use translations from my JavaScripts.</p>
  
  <p>The bundle BazingaJsTranslationBundle seems to be good, but after I tried it I don't think it fits my needs. It generates all the translations for all my application's bundles. It can be heavy to load.</p>
  
  <p>Do you know other bundles or tricks for that ?</p>
  
  <p>Thank you for your help.</p>
