Javascript Practice 40: JS Hero - XOR

 

Question: 

Write a function xor that takes two Boolean values. If both values are different, the result should be true. If both values are the same, the result should be false.

I.e.: The calls xor(true, false) and xor(false, true) should return true. The calls xor(true, true) and xor(false, false) should return false.

Answer: 

function xor (boo1, boo2) {

let xor = (boo1 || boo2) && (!boo1 || !boo2);

return xor; 

};

> so if boo1 & boo2 are both true (or both are false) then variable 'xor' will store the value false and in all other cases it will store the value of true
