For kicks I just checked my minified code of my app for equality and inequality 
checks and there were 5466 instances. Just adding strict equality would add 3KB 
to my file size. (out of 1.8 MB, but still...)

It would be an interesting exercise to see much much adding null initialization 
would add to file size. I would guess that it would be significant.
