Convert boolean result into number/integer

Question

I have a variable that stores false or true, but I need 0 or 1 instead, respectively. How can I do this?

Answer 1

The unary + operator will take care of this:

var test = true;
// +test === 1
test = false;
// +test === 0

You'll naturally want to sanity-check this on the server before storing it, so that might be a more sensible place to do this anyway, though.
