I am sure you know this, but for the record, Javascript has two equality 
operators, '==' and '==='.

The double form attempts to coerce the left and right sides to the same 
type, the triple form does not.

'1' == 1 returns true

'1' === 1 returns false

The moment I discovered this, I changed all my operators from the double 
form to the triple form. Now I no longer have surprises of this nature.
