If that sounds like jargon, don’t worry. Here are several advantages that come with a wide understanding of XOR: Enhanced Logic The OR operator || uses the right value if left is falsy, while the nullish coalescing operator ?? uses the right value if left is null or undefined. Viewed 2k times 0 . If either operand is NaN, return false. @RobertGrant - The xor operator in JavaScript converts its operands to 32-bit integers (using the ToInt32 internal method—see Section 11. Those two are not the same because a ^ b is a bitwise xor function instead of a logical xor function. It compares equivalent bit values of operands and returns 1 if the bit values are different or 0 if they are the same. If one side is zero then it will return the non-zero number. Mastering the operations of JavaScript XOR can provide certain benefits for developers. If a value can be converted to true, the value is so-called truthy. Ask Question Asked 3 years, 9 months ago. The XOR operation returns 1 (true) if the inputs are different, and 0 (false) if they are the same. So, if a = 1 and b = 2 , then a ^ b=3 but you would want a falsy value because both a and b are truthy. Javascript XOR operation (trying to understand!) 1. 7. Otherwise, compare the two operand's values: Find XOR between each valid integer using this logic; Rule 1 : If both bits are 1 then XOR’ed bit will be 0.
