Bitwise XOR Assignment Operator (^=) (JavaScript)

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

Syntax


result ^= expression  

Parameters

result
Any variable.

expression
Any expression.

Remarks

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.
