bitwise xor assignment


Performs a bitwise exclusive OR on a variable and an expression and assigns the result to the variable.


result ^= expression
Any variable.
Any expression.


See Remarks.

var x = 5;
x ^= 12;
// result: x = 9


Using the ^= operator is exactly the same as specifying:

result = result ^ expression

The ^= operator looks at the binary representation of the values of two expressions and does a bitwise exclusive OR operation on them. The result of this operation behaves as follows:

0101    (result)
1100    (expression)
1001    (result)

When one, and only one, of the expressions has a 1 in a digit, the result has a 1 in that digit. Otherwise, the result has a 0 in that digit.
