Webcrypto {3nc0d3_d3c0d3_3nc0d3} XOR Starter - Points: 10 XOR is a bitwise operator which returns 0 if the bits are the same, and 1 otherwise. In textbooks the XOR operator is denoted by ⊕, but in most challenges and programming languages you will see the caret ^ used instead. For binary strings we XOR bit by bit: b'0110' ^ b'1010' = b'1100' .
