You can even get more thrifty by saving on vars as well :) and conserve some more electrons besides those affected by semicolons.

   _obj.publicVariable = 'bar'
   _obj.publicMethod = function(){}

Personally I cannot type any statement without an ending semicolon, it is a mannerism that stayed with me since I had to learn Pascal. It makes it difficult for me to do anything useful in Python and I am actually contemplating to see a therapist for this.
