What if I send null as one parameter and try to perform operation on it in the function like adding, then what would the function return?

I think null will be considered 0 for the addition operator. For example: function sum(x, y) { return x+y; } document.write(sum(10, null)); This will print 10.

null is nothing. 0.

javascript amazes me sometimes. so null (not nothing btw) will be interpreted as 0?
