Q: 

FB permissions, fb tags vs. javascript

Is my understanding correct, that in FaceBook development I can request application permissions (for user data, posting to his wall etc.) in 2 ways

  • by using some static permission-requesting fb-tags in html code
  • or by using facebook JavaScript libraries/objects for dealing with permissions?

If so, are these ways serving the same purpose or different ones? Which should be used when?
