Why is there no logical xor in JavaScript?

Question

Why is there no logical xor in JavaScript?

Answer 1

How about transforming the result int to a bool with double negation? Not so pretty, but really compact.

var state1 = false,
    state2 = true;
    
var A = state1 ^ state2;     // will become 1
var B = !!(state1 ^ state2); // will become true
console.log(A);
console.log(B);
