## turboreload.js.coffee
# Call turboReload() on any page to update the content of the current
# page without disturbing the user.
#
# 1) It is faster than a normal reload because the browser doesn't fetch or
# parse any scripts or stylesheets in the head. Instead, we just replace the
# body contents with the updated body.
#
# 2) It doesn't cause the page to scroll or flicker on the user.
#

turboReload = ->

  # browserCompatibleDocumentParser, borrowed from TurboLinks.
  #
  # Use createDocumentUsingParser if DOMParser is defined and natively
  # supports 'text/html' parsing (Firefox 12+, IE 10)
  #
  # Use createDocumentUsingDOM if createDocumentUsingParser throws an exception
  # due to unsupported type 'text/html' (Firefox < 12, Opera)
  #
  # Use createDocumentUsingWrite if:
  #  - DOMParser isn't defined
  #  - createDocumentUsingParser returns null due to unsupported type 'text/html' (Chrome, Safari)
  #  - createDocumentUsingDOM doesn't create a valid HTML document (safeguarding against potential edge cases)
