Which do you prefer '_abc' or 'abc_' as private variables?
I just read [google javascript style guide](http://google-styleguide.googlecode.com/svn/trunk/javascriptguide.xml?showone=Naming#Naming) and knew that they prefer trailing underscore as private varibles.

I've rarely seen 'abc_' style at javascript code, so I'm just curious.

Which style do you prefer as private variables? leading underscore or trailing underscore? (or nothing?)
