WebMar 30, 2024 · The Bitwise AND Assignment Operator is represented by “&=”. This operator uses the binary representation of both operands and performs the bitwise AND operation and then assigns the result to the left operand. This can also be explained as applying the logical AND operation to the first operand and second operand and after … WebBitwise XOR operator evaluates to true if both operands are different. To learn more about bitwise operators, visit JavaScript Bitwise Operators. Let's see how the above program swaps values. Initially, a is 4 and b is 2. a = a ^ b assigns the value 4 ^ 2 to a (now 6). b = a ^ b assigns the value 6 ^ 2 to b (now 4).
