+Returns `true` if only one of the arguments is `true`, `false` otherwise.
+
+- Use the logical or (`||`), and (`&&`) and not (`!`) operators on the two given values to create the logical xor.
+
+```js
+const xor = (a, b) => (( a || b ) && !( a && b ));
+```
+
+```js
+xor(true, true); // false
+xor(true, false); // true
+xor(false, true); // true
+xor(false, false); // false
+```
