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

You can also add 0, use shift operators or xor:

val + 0;
val ^ 0;
val >> 0;
val >>> 0;
val << 0;

These have similar speeds as those from the others answers.
